Bug

I have got a problem, I work in a project since 6 month and this morning I change my map name an Unreal Engine crashted and whent I restart Unreal all my maps were deleted, my player controller too .
Please Help me I don(t want to remake all my game.

Do the assets still exist in File Explorer? If so, then try renaming the level to something else. It probably has the same name as an existing editor file. Also, this is the wrong section.

I search and found that all my animations were deleted and game mode, player controller,character … doesn’t work anymore

Well… I guess they are gone then. You should make backups next time.

Thanks
