I’m using a 1070 and have issues with the screen occasionally going black during gameplay, though the other issue - of the game crashing whenever I tried to switch applications and changing other GPU-related settings (obv have W10 & GPU drivers & everything else fully-updated - is now fixed.

Just in case anybody else comes across this issue who also got this game through an NVIDIA 30 Series bundle, what I had to do was re-redeem the code in GeForce Experience for it to start working again. I noticed the redemption period ends 2/10/21 so maybe this won’t work in the future.

i had exactly the same problem. I’ve tried everything, but it didn’t work. Then I logged out of my account and then I signed in and the problem was solved.
I say try this first before you do all the other stuff because it takes a lot of time.
Also you need to verify your account to: ‘activision’.
So back in christmas, I downloaded black ops Cold War because it was free, now I wanna play zombies but I can’t play, it just says “buy now” because I uninstalled it
Keep in mind that I had installed the game and it didn’t let me play. Was it a period when it was free to play or permanently free for those who downloaded it?
just fix it from your end activision blizzard you greedy cucks
Same Error played 2 days durring the free event now it says “You can’t play Black ops Cold war yet”
I would have liked to play the free event to see if I wanted to purchase but if they can’t fix the issues with playing for free or Dev error 6634 in Warzone I guess I will say no purchase for me.
this game is a joke now. Plunder, battle royal, i get DEV ERROR 6634 on my PC about twice a day. Game freezes, i lose ALL achievements, and it closes the game. this has been going on since the end of JANUARY!!! come on now. FIX THIS!
try uninstalling origin app sgtfluffy. I tried everything to fix that dev error and it turned out to be the crappy EA Origin app causing it the whole time…
I realized after trying and failing with all of these solutions, that i was signed into my alternate blizzard account. This was my solution.
Ive had this issue since the last update on Tuesday 22/06/21, They say that the game I bought was not under the email address I sent a ticket however they have found the purchase and asked me to send a copy of my driving licence, which I sent 18 hours ago, and still no access
Did u ever find a solution. If you did please tell me.
Found the issue, i was logged onto another account
