Here’s my update, I’ve done these things:
- forcing the game to use only the RTX 4060 in Windows/NVIDIA settings

- disabling Hardware Accelerated GPU Scheduling

- clearing the DirectX shader cache: UE5 shader corruption can survive reinstalls

I’ve updated my drivers again and tried the latest game update. It unfortunately hasn’t fixed my issue. After changing the relationship status to BFF it crashed again (but no blue screen this time – can be important to note).
The only thing I haven’t done so far is updating the BIOS, that felt like a too big of a step if it’s potentially not a firmware issue but an in-game issue.
Your suggestion to report it via support from the official website makes perfect sense, however I’m not sure if I know where to find that. Can you direct me to a link where to report that? Or do I do that via Steam or some other platform?
Thank you.
(EDIT: I found another related post on here Hard System crash on relationship action — RTX 4060 laptop (Win11))
EDIT 2:
I ended up updating my BIOS too, to the latest version downloaded from the official MSI website. I just tested the game gain and it still keeps crashing after relationship change.
