Bugged block outlines, game crashes when block is interacted with, and random crashes

I've been seeing bugged block outlines while playing Minecraft and usually if I interact with that block, it freezes my game. I've had to reload the game but after a while the bug shows up again. I have experienced it recently but its still occurs while playing the game, even after I reload Minecraft and my computer. When I see it I try to leave it alone but the game does eventually crash a while after seeing it. I also experience random crashes a lot and they mainly happen when I enter a world, but there isn't a certain amount of time before it crashes. On top of everything I do understand there's a lot of people reporting bugs, but this is affecting gameplay quite a bit and I'd hate for others to experience it. If you see this, please consider looking into it.

Sincerely,
