During this week I found similar error in another game on UE4 (Ace Combat 7).
After updating nvidia drivers to 440.26 all works fine.
I'll try to observe behavior of UE4 games for next several days.
If all goes well this issue will be closed
I didn't have any crashes during last month, it seems it was nvidia driver problem.

System Information

Symptoms
Game crashes at specific areas of map/during cutscenes/while rotating camera.
There is some probability that game will crash at specific moments.
I found 2 types of errors in clipboard:

Got this problem at proton 4.11-7 and 4.2-9.
Reproduction
I don't know if it's problem specific to my system/hardware configuration, but I found nothing similar here or anywhere else.
Places where game will likely crash at the first level (with enemies):
Couldn't go further because of this problem.
