Hi. I accidently opened my ue 4 project in ue 5 ver(not copy) and made some progress, saved couple of levels. And when i revert project to ue 4 ver, i can’t see levels saved in ue 5 ver. Is there some way to open it or save in ue4 format, like in 3ds max for example i can save my scene as a previus ver? Thank you.

You could try to create a new UE4 project and use the migration tool to migrate your levels to the new project (from the ue5 one).
Converting in place is a really bad idea, btw.

Didn’t work 
After you save it with ue5, there is no turning back. You can try reverting your changes with source control system that you use. If you’re not using it, I think that’s a good lesson learned for you unfortunately.
