I'm having the exact same problem too on an Xbox One S playing v1.16.201 with plenty of unused storage space (593GB Internal & 172GB External).....can't update worlds that I've already purchased through the Marketplace & can't install new worlds. I am NOT gonna uninstall & reinstall this game after I have done so a handful of times in the past. I have alot of worlds & that eats up too much of my time to reinstall all of my worlds over & over again whenever the game has a bug. Mojang needs to fix this issue ASAP.....alot of us have invested a good amount of money into Minecraft in general.....marketplace, etc. I know I have spent well over $500 just in Marketplace content alone. Please fix this issue, Mojang. Also, would it be possible in a future game update to allow the uninstalling/reinstalling of the game WITHOUT deleting the world save & resource pack folders. Maybe a tick box in the settings that would allow the player to choose whether or not they want their world save & resource pack folders to be deleted upon unstalling. That way IF an issue arises that can be temporarily resolved by uninstalling/reinstalling the game, you wouldn't have to go through the time & trouble of reinstalling all of your worlds. Alot of Minecraft players are just casual players & don't have many worlds but alot of us do.
