Randomly crashing from every server with various different reasons (VarInt too big, length wider than 21-bit, badly compressed packet, incorrect header check)

Ever since I got my new PC I've been having an error where I randomly and sometimes constantly disconnect from any server I'm on with no fix in sight.
Here are some of the crash screens: https://imgur.com/a/7dteepp (sorry for unicode font lol)

I've noticed that it's happens frequently whenever I approach a large group of mobs in something like an xp farm, or just flying around with an elytra.
Any help would be appreciated.
