Every time I try to render a somewhat heavy scene blender freezes my whole computer and do not come back, I have to turn off and on again. And every time I try to bake the same scene blender crashes and sometimes freezes the computer as well.

Just rendering this scene of a chest with high definition textures or any baking. Something weird is happening, when I bake with 1000 samples the PC freezes but within 10 minutes blender crashes and the PC is fine, but if I put with 200 samples it just never unfreezes.

Did you basically checked you do not run out of memory? Use your task manager while baking or rendering…

This file will indeed run out of memory, when rendered it will not fit fully in 8GB memory. You can reduce subdivision surface levels or other details in the scene.

When you system starts running out of memory it will start swapping, which can significantly slow down the system or even freezing it, this is outside of Blender's control.

I had checked, it does run out of memory, and I found a way to work it out like you said, Bretch, I reduced the textures and the SubSurf details. I thought that the freezing part was a big bug :c. I'm gonna be careful of my memory now. Sorry for the waste of time report..

Wrong even on half of 16GB RAM, Blender 3.0 freeze Windows in 131MB file with 400MB textures and 1lvl of subdives
it's just bad coding.
