I hope they bring the far lands back soon.
I got the same thing!
Try uninstalling and reinstalling the game, make sure to backup your worlds. If the problem stops, it's good. If not, try updating to game to see if that'll fix the issue.
Having too many devices on your microsoft account (e.g:10) can cause minecraft to think you don't own the game, and that's why you should unlink all of your devices except the one you're using.
For unlinking devices: https://account.microsoft.com/devices/content
It also tells me that i should update my drivers when i already did.
Make sure you're connected to the internet.
I experienced the same issue. :/
