Very odd issue with Warhammer 3 shutting off my PC

[Baskerbosse]

Hello,

I've run into an odd problem while playing Warhammer 3. Right after a specific battle my PC shuts off completely during or right after the loading screen. Has anyone run in to something like this before? It seems to only happen in this game and at this exact moment.
I've recently installed an AIO which would be my first suspicion if not for the fact that, again, it only happens in this game.
Temps for CPU and GPU never go above 65°C.

 

PC specs:
MB: ASUS ROG STRIX X570-F Gaming
CPU: AMD RYZEN 3700X
ASUS TUF RTX 3080 10GB GAMING OC V2 (LHR)
RAM: 32GB DDR4 3600MHZ
CASE: FRACTAL DEFINE R6
STORAGE: WD BLACK SN750 M.2 NVMe SSD 1TB

Welcome to the forums!
What PSU? Do you have a UPS?

Also, very strange question, but did you get that 3080 right around launch?

Helli again,

Thanks to Oddood for the suggestions
The problem has been solved in a different, very silly way though.
Since it only occured in Total War Warhammer 3 and no other game, I kept trying to recreate the crasch in other scenarios in the same game. Nothing.
Then I tried loading the autosave file from before the problem-battle initiated. There I moved my character a bit and ended the turn... This fixed the problem completely. The game and the PC work flawlessly now... This has been a cursed experience...
