PC Crashing after closing a game

Hi all, I'm having an issue with my PC where it keeps crashing after closing games. It runs absolutely fine with no issues whilst playing, alt-tabbing, doing everything else like browsing the net or streaming etc. It ONLY ever happens when I close a game. Everything just freezes and becomes non-responsive. Sometimes it automatically shuts down on its own, other times I have to do a hard shutdown by holding or pressing the power button on the tower. It seems to be fairly inconsistent and I can go through a bout of it happening every single time, and then not happening at all for a week and then it suddenly returns again. I believe it started happening roughly around February of this year but not 100% sure.

Any help to resolve the issue is much appreciated.

I've tried the standard things like drivers updates etc. Hasn't helped. I also did all the cmd prompt stuff (sfc /scannow and DISM). It found a repaired some stuff but didn't solve the problem.

System:

Windows 11 - 22H2 - 22621.1555

NVIDIA RTX 2080 Ti (MSI Gaming X Trio)

A quick check of the reliability history shows the below as occurring.
