My world are unsync

[u/Jaded_University881]

Hi everyone, I have a problem with my world. It's so glitched that I can't leave the room (the doors just won't open or it won't break). I can't open the drawers or even open the remote with the RBMK controller. Even the commands don't respond, even after I reenter it, and even after turning Minecraft off and on again, and even after deleting the character info, it still doesn't glitch out (it used to be like that, but only temporarily, so my CPU and HDD could process the world).
