I tried to find one way or another by myself, but it didn't help me.
A blue screen popped up while I was working.
I didn't worry much because I just saved it before the crash.
But, the project did not open.
I tried the method shown in the link, but it was not solved.

It didn't help to install other versions.
What can I do?
