Can't open level after updating to 4.21.1

Hey guys.

Yesterday i updated my engine from 4,21,0 to 4,21,1
and when i open up my project i get this message:

Failed to open map file. This is most likely because the map was saved with a newer version of the engine.

i can open the project and all my assets will be in the explorer but any level i open will just welcome me with a black screen.
wonder if anyone could help me find a way to get acces to my level again?
