World was saved in a newer version error.

Cannot enter any worlds.

Whenever we try to enter a world created in the last 8-10 days we recieve and error that says "World was saved in a newer version, loading this world could cause problems."

 

The version stated on the world is 20w46a but the application version is 1.16.4

 

how do we fix this issue? The game worked fine yesterday.

 

Regards,
