Crash (BSOD) after launching game in window mode

Hi,
I’m experiencing contant crashes after launching game in “Window Mode”. I’ve changed that setting after experiencing “D2” process freeze while trying to use portals or entering caves.
Right now 5 sec after “connecting to BattleNet” in character select menu my PC crashes.
Additionally GPU report 63% usage right before crash.

Dump details:
On Sun 22/08/2021 21:14:55 your computer crashed or a problem was reported
crash dump file: C:\Windows\MEMORY.DMP
This was probably caused by the following module: [nvlddmkm.sys]
Bugcheck code: 0x133 (0x1, 0x1E00, 0xFFFFF8001EAFB320, 0x0)

Bug check description: The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL or above. This could be caused by either a non-responding driver or non-responding hardware. This bug check can also occur because of overheated CPUs (thermal issue).
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 471.68 , NVIDIA Corporation).
