Brand new PC: Game keeps randomly crashing

Hello there,

I just got a new high-end gaming laptop and was looking forward to playing Sims 4 on it. I have played for years and have never had this issue on my old laptop (which was otherwise performing pretty badly). The issue is that Sims 4 constantly crash for no apparent reason. I don't get any error message and the application just seems to close on its own (it kinda freezes for a bit and then a quick flash of white or black screen before it closes).

This is on a freshly set-up PC with W11 where the only things I have downloaded this far is the EA launcher, Sims 4 and my current browser. I have followed the troubleshooting guide and otherwise tried most tips that I have found online. Steps include (not neccesarily in this order): 
- Uninstalling and reinstalling both the game and the launcher
- Deleted mods folder and cache-file 
- Moved entire Sims folder to desktop and multiple fresh saves 
- Checked that drivers are updated

I dont have any mods or custom content downloaded, and it doesnt seem to matter if I load into a game or start a new game. I dont see any clear pattern to it happening either - as it can happen after 5 minutes or after 2 hours (max time before crashing) and there isnt any particular location or action that my sim is performing that I notice.

I just want to get back to playing Sims 4. Please, could anyone tech-savy help me with this? Ive included the dxdiag for a crash that happened after 2 hours (DxDiag2) and the most recent for a crash that happened when restarting and playing for like 5 minutes (DxDiag3). Ive also included a screenshot from monitoring CPU and GPU while playing, as I noticed something that may (or may not) be of relevance. See the attached picture where it seems that the GPU goes idle at the approx same time as the crash happenes. 

Can anyone please help me with this?
