Unable to do anything in-game after changing my Password to my account

Ok I was too lazy to type in all versions, but basically after changing my password for my account, I've been unable to join anything. Not my realm, my worlds in singleplayer, or even multiplayer servers like Hypixel.

Whenever I try, the game freezes on the dirt screen and then crashes for some reason.

I did look at my crash-reports file to see if anything appeared, but nothing appeared in it.

This constantly happens regardless of what I do, and I'm not sure what else to do other than report it.
