Bug that says you do not have enough storage space when you have enough space.

Hello Mojang, I have a bug regarding the new hotfix 1.16.21. It says that when you try to play/make a world "You are almost out of storage space! Minecraft has disabled this feature until you clear up additional storage space." I have over 20 gigabytes of storage and it still seems to say that. Please fix the bug soon. I'll be counting on you!
