Game Freezing and going to white screen when saving

Since I ran the July 1st update, my game has been freezing a lot, and every time I save (which is a lot so I don't lose progress), my game goes to a white screen or back to my desktop. It does this a few times before the game comes back and runs normally. It is just very frustrating when I want to play. I took my mods and save folders out before I ran the update, and since finding this issue, I have run a repair as well. I am currently running with no mods or cc apart from MC command.

Has anyone found this issue as well, and anything to help stop it?

Thanks!
