Maybe this is why games are freezing and crashing.

This can't be normal that CK3 is using 19GB of memory and climbing. Even with conversion mods this thing shouldn't be using that much memory. This is before I even start a game and I'm just sitting on the menu screen. I would imagine as the game goes on the memory usage will increase, no? This would explain why some people can play for an hour or so before their computer poops the bed and crashes, or freezes their computer.

Memory leak?

Freezing or crashing the whole computer is a symptom of the Windows 11 24H2 issues; I don't think memory shortages for an app could ever cause that. But it can cause game crashes of course.

For me, with all DLCs, in the main game menu CK3 uses 5.8gb. At late-game starts, 8-9gb. After running 50 years in observe mode, still under 9mb. So I don't know how yours gets to 19mb!

Can you attach an affected unmodded save here please, for others to try in their setups?

I have similar case regarding RAM. Reach 20MB. But I have a lot of mods also I pass around 100 year with 4th character.
