Game crashes on PC

I finally managed to get the game to start on PC again to a point where I’m actually seeing the main menu (click to play). When I select my character the game goes to the loading screen and crashes shortly thereafter before getting into the actual game. The game used to work until about 6 weeks ago.

I have reinstalled the game, deleted cache folders, battle net cache, Nvidia cache, rebooted my PC, tried the newest Nvidia drivers, reverted to a September version, checked Windows updates, closed all programs, uninstalled Discord, uninstalled the Nvidia studio, etc. So basically I think I pulled every trick in the book.

Today I managed to actually get a crash with an error message:
“cannot allocate memory program is going to exit”

I was lucky enough to have my TaskManager open and saw that there was a memory spike to 16 GB when the game crashed. I have tried to replicate this since then and tried manually increasing the size of the page file - no luck getting into the game nor getting the error message again. Currently the RAM isn’t even spiking anymore before the crash.

Any ideas?

I’m running an i5-10400, RTX 3060, 16GB RAM, Win11 64 bit.

DXDiag shows a few entries for the game…

This was the only error remotely around the time of the crash so we can probably rule out a driver conflict or an incompatibility.

Edit
After tinkering with ProcMon I was able to find out pretty much what happened right before the crash:

So basically it’s trying to read a bunch of patch files that aren’t there and then it communicates with the server, creates the dump report via WerFault.exe and ultimately closes all threads.

I have already tried to repair the client with no luck. As far as I can tell with my limited knowledge either the update isn’t downloaded in full or it isn’t applied correctly. The game then dumps because it’s trying to access a resource from the patch that doesn’t exist.

I have already temporarily turned off Windows Threat Protection. I don’t have any other protection software running. I checked any processes that might have a handle on DiabloImmortal.exe - none there, all clean.

If you’re curious as to what I have tried in detail, it’s documented here:
