I've been dealing with this for over a year (probably even longer) and I have a pretty decent computer, it runs several LLM instances for example. Even upgraded to 64 GB RAM a few months ago. I did turn off 'Hardware accelerated GPU scheduling' and that did make a little bit of a difference. Also been trying to increase and decrease the available virtual memory, but increasing it only made it worse. Only thing that could still be an issue is my SSD, which is a bit outdated compared to my other specs (Samsung 970 EVO Plus). Also, playing without any mods gives way fewer crashes than playing with them on.
I will try other things to help mitigate the crashes, but this is truly disheartening as I have played CK3 with mods for years without this crashing issue.
