probably something corrupted in your MC files. I would suggest deleting all MC files but keep your resource packs and saves. Them, just redownload minecraft and get the new files and put back the packs and world saves. It worked out for me but idk. I wont guarantee it would work so just to be sure, look up other ways
Try looking at your save data looking for any weird files, recently I had a problem of random data corruption, and I had some 'conflicted copies' and even a session.lock, I'd suggest googling the file name's trying to find any fixes if that's the case, sorry if I'm no help and hope you can get the issue resolved!
