Facing Errors while migrating 4.27.2 project to UE 5.0 EA2 5-0

After I migrate my UE4.27.2 project to Unreal engine 5.0 EA2 build I’m getting an error called “cannot load the map because it’s saved in newer version of unreal engine”. What can I do to fix this issue? Is it possible to downgrade my ue4.27.2 project to UE 4.26?

What i did was Delete everything except the COnfig file and The Project setup file and opended(Rebuild in UE5) and it worked for me. can you give me a SC so that i can recreate the problem ?

Yeah I have the same problem. Even tried to migrate some assets to UE5, in the 4.27.2 editor it do not give any error, even all the files show up in windows file explorer but when open the projects can not see any files there :(. So anyone find a solution.
