Monitor is freezing at the last frame shown and computer stops running the game, but doesn't close it.

Last time i had something similar was in a modpack but the issue there was allocating of ram, but i allocated 12G and it didn't help.

it happened in earlier snapshots too, but not in the previous full releases.

I don't see a particular pattern to this issue. Maybe it has to do with autosaving, or maybe with inventory access. I can't be more precise on that.
