Game Black screens randomly whilst playing

Recently when I’ve been playing war thunder its just been giving me a black screen and then restarts my PC. Using the event logger i can see that it gives me the error code:
“The RstMwService terminated with the following error:
%%2684420176”
It doesn’t seem like its associated with anything (like loading in to a match etc.).

I’ve only been able to mitigate the problem my turning on DLSS. I still crash, but instead of it taking around 30 minutes it takes about an hour.

I know its not a hardware problem, as this occurs only in War Thunder, no other game or app.
I’ve tried this, but to no avail:

  • Checked my CPU and GPU temperatures with benchmarks, and they are in normal ranges.
  • Clean reinstall of the game (deleting all files and reinstalling)
  • Turned off any overclocking’s

I have played War Thunder for almost 2,000 hours over 4 years and 3 different computers, i have had performance issues sometimes but nothing like this.

Incase its useful, here are my system specs:
CPU: Ryzen 5 5600X
GPU: MSI GeForce RTX 3060 12GB
32gigs of RAM
1TB NVMe drive
