Problem details:
I was editing my map and suddenly the editor started crashing so I saved the map and restarted osu. Now when I try edit the map I can only see the menu bar, the rest is just a black screen. Also - when I try to play the map from normal mode the game either crashes or I get error and map won't open. What can I do about it?
Or at least, what can I do to not lose the map?
Other maps works perfectly fine, it's just that one that won't open. I saw some threads about similar/the same problem and they fixed it with pressing ctrl+alt+del but it doesn't work for me. ALSO, for some reason I cannot go into windowed mode, it's always fullscreen for me. Lately osu is just working weird to me, like when I go to the desktop with windows button and I want to go back to osu I gotta press the osu icon a LOT of times to get back because it's showing for a sec and then I'm on the desktop again.
EDIT: ok nvm I've just tried to use the repair osu shortcut and most of my maps got deleted, including the one I did
