So after migrating my Mojang account to a Microsoft account I've been trying to make a new world but it didn't work.  I tried with and without mods, data packs, addons, etc... but nothing worked.  All that happens is that it makes it look like it's loading but then just gets frozen or glitched and it doesn't even completely load.  I think it has something to do with the migration account thing going on but either way this must be fixed or I will be very upset since I spent both my money, my time, and my imagination on something that ends up being wrecked.
