My game keeps crashing from time to time, and I can't exactly pinpoint when it happens.

I noticed that it crashes when I travel between two villages on a horse, somewhere midway, maybe when either village chunks are loading. After the initial crash, the game keeps crashing every time I load it. The only temporary solution to stop crashes is lowering the number of render distance to 2-4 (instead of usual 22). 

The crashes also happen sometimes after getting close to villages or trying to push them, so crashes might be related to villagers too.

I also noticed that my GPU activity peaks to 100% right before the crash, so it might be related to that.

I get the same crash report every time:
