Cubase deleted my session.

This happens every time: I saved and closed my project and Cubase just hangs and spins the rainbow wheel until have to force quit. But at this point, the session had already been saved and closed. I just wanted to open a new session, but had to force quit Cubase and restart.

However, now this time it is saying my session doesn’t exist.

Is there anyway I can work in Cubase and still keep my session?
