Hi there, I have a bit of a problem. My game keeps crashing at random. I tried reinstalling the game, reinstalling drivers, clean instalation of drivers, disabled nvidia reflex and dlss etc. Nothing works. All I can think is to do a clean windows reinstalation at this point, not sure if this helps tbh…
Below is a link with an error that I got from the crash logs.
<CPU_Details> 13th Gen Intel(R) Core™ i9-13900KF
It could be the CPU, depending on how long it ran outside the intended specs before the necessary BIOS update. Some of them don’t improve with the update.
A few quick observations from your dump:
BIOS is already on F12 (Jan 7 2025) – that build rolled in the August ’24 stability fixes, so you hopefully aren’t effected by the CPU problems. You could try going to https://www.intel.com/content/www/us/en/download/15951/intel-processor-diagnostic-tool.html and running the tool. It might give you more information.
The crash itself is an EXCEPTION_ACCESS_VIOLATION reading from 0xFFFFFFFFFFFFFFFF. In 64-bit land that’s usually a “sentinel” or nullified pointer, meaning the engine’s trying to touch an object that’s already been freed or zeroed out.
If you look at your “Crashing Thread” stack, you see the same four addresses repeating in a tight loop:
DBG-ADDR<00007FF7D910154F>()
DBG-ADDR<00007FF7D90F9B8C>()
DBG-ADDR<00007FF7D910E99F>()
DBG-ADDR<00007FF7D9101552>()
That pattern screams “high-speed iteration” – likely walking a list of players or voice-chat participants to update status/UI.
The voice-chat log timing is the clincher:
[VoiceChat] MemberRemoved[ERR] [VoiceChat] ==[VC] Member not found for member modifyIn other words, the system deallocates the player record, then ~11 ms later the update loop still tries to poke that same entry.
The crash happens because the game is trying to update info about a player who just left. Their data is already gone, but the engine didn’t catch that in time, so it hits an invalid memory reference and crashes. It’s like racing two cleanup crews—one deletes the room, the other tries to adjust the curtains that aren’t there anymore.
This FEELS like a bug, but I’m not really sure. It’s hard to say.
Try staying out of voice chat (disable auto join) and see if the random crashes stop?
Also, some steps that are always good to try if you haven’t already (in order)
Thx for detailed answer.
I did download the program to check CPU, it was all green after test.
Checked the files of the game, it did find something and fixed it, after that I played for 3h without crashes then it crashed again with this -
This was mid game, so no one was leaving etc.
Now I am trying without voice chat.
UPDATE
Its even worse when I leave chat. Before the game crashed to desktop, if I leave voice chat, my whole PC is crashing and rebooting.
Can you try actually disabling voice chat entirely so it never even attempts to join? You can do it through Social settings.
You have several audio devices on your PC – I would recommend disabling some as a troubleshooting step. Personally I disable all the ones I don’t use.
| Device | Driver File | Driver Version |
|---|---|---|
| Realtek Onboard Audio | RTKVHD64.sys | 6.0.9733.1 |
| Generic USB Audio Device | USBAUDIO.sys | 10.0.26100.4484 |
| NVIDIA GPU Audio (HDMI/DP) | nvhda64v.sys | 1.4.3.2 |
| Razer Kiyo (Microphone) | USBAUDIO.sys | 6.2.9200.16547 |
You can disable them from Device Manager. Search for Device Manager in the Windows search bar, then right-click the audio device and select “disable device”. Focus on disabling the NVIDIA Virtual Audio Device (WDM) (if it’s there) as well as any audio devices you don’t actively use (i.e. the Realtek onboard audio if you only use a headset).
Note: Be very careful in Device Manager. Disabling devices can cause problems if you disable the wrong ones. Things like Audio devices are low impact and can be re-enabled. Do not disable anything else in here unless you know what you’re doing.
Can you please also post a dxdiag?
Windows key +R → type dxdiag and push enter.
Wait for the green bar (bottom left) to finish.
Click “Save All Information.”
Upload the txt document contents to pastebin.
What antivirus software are you running? The first crash report showed Avast I think it is – you don’t need this. Just run the standard built in Microsoft Defender. It’s proven to be excellent, safe, and great for games. I would highly recommend uninstalling any kind of third party security product, either antivirus or firewall. Just use Windows Defender AV and Windows Defender Firewall.
You could try running the “Windows Memory Diagnostic” to make sure this isn’t being caused by some weird issue with your RAM.
I use Norton 360 Deluxe as antivirus.
Here is a DxDiag
I disabled the audio sources, only left the headset and Nvidia high definition audio.
Will update later how its going.
Remove it. Completely. See my note above.
Norton is known to cause serious issues.
It injects kernel-level filter drivers into your system, scrutinizing every operation at a fundamental level.
This constant overhead introduces latency, resulting in performance degradation, increased input lag, and unpredictable issues during gaming sessions.
Even if it’s just temporarily. I highly recommend removing it in its FULL AND COMPLETE entirety.

I recommend running this, rebooting, then running it again and rebooting again.
Once you’ve done that; from admin command prompt run fltmc filters and paste the output here. It will tell us if you have anything running still (and if there’s anything weird). The output will look something like this

Now I will try with uninstalled norton.
Update
I uninstalled norton and this is what I’ve got:
UPDATE
I played 3h without crash after uninstalling my Norton antivirus. Will play it tomorow some more.
UPDATE
Its still not it.
Just crashed, relaunched the game and crashed again within 1 min…
Hi Dodo,
Sorry for the delay in getting back to you.
Based on the provided crash logs, the recurring EXCEPTION_ACCESS_VIOLATION errors point to memory instability or software conflicts. The error addresses are inconsistent (0xffffffffffffffff, 0x0000000000000001, 0x0000000000000000, and others), which is characteristic of memory corruption, not a singular, reproducible game bug.
Please try the following. As annoying as it may be, they are critical in attempting to solve the problem.
Stop and test your game after each step (except Step 1, where you either stop if there’s an error, or we rule out RAM being an issue).
Step 1
Test your memory for as LONG as possible with Memtest86.
https://www.memtest86.com/downloads/memtest86-usb.zip * Run the imageUSB.exe tool from the ZIP file with your USB plugged in (THIS WILL ERASE ALL DATA ON THE USB STICK).I really think this is the most likely cause.
If this detects anything, do not continue. You have faulty RAM.
Step 2
Stress test your system.

Step 4
Step 5
(These next two are almost never the fix for anything,
but they have been on very rare occasion, so just give them a shot!)
Step 6
Step 7
Step 8
Best of luck.
If you are unsure on any of these steps, let me know.
Step 1
Yea, after 45 mins of test it found over 30 errors.

Do you think that buying new RAM will solve it?
Should I complete other stress tests etc?
Thank you for your time and help with this issue. I wouldn’t have solved it alone 
Also I updated my Bios to the newest version that got released 27th May - F13c. Strangly my Gigabyte control panel didnt see it was avaible.
There are so many things that could cause the RAM to test bad, it’s a bit of trial and error.
Do you have a friends computer you can put your memory in? Or does your friend have some memory you can put in your computer to re test.
For context; it’s usually the RAM, but can be the CPU or motherboard also.
Unfortunetly no one has ddr5 slots 
I dont want to be overyly happy buuuut, since bios update I havent got any crashes yet. I played yesturday for some time, today for more than 2h and no crash. Could it be… xD
I haven’t ever tried that as a fix before, but it’s not beyond the realms of possibility.
Good luck!
Yes, it seems, updating the bios fixed all my issues.
I had problems not only in OW
In other games on Unreal Engine 4 it crashed often with a fatal error etc. but I wasnt connecting the problems before.
Now after the bios update everything is running smoothly without any problems.
Awesome!
Can you mark the post as solved
Thx again for help
