So yes, I was working on my project and I really want to finish this stuff. However, this morning (noon actually) when I loaded the project on Cubase all seem to load nicely but when that was done, Cubase just quit with no explanation - right before showing the edit screen. What a great piece of software (I like working on it though).
I once had similar trouble and I remember a friend helping out. Turns out that deleting this folder (or renaming it "*.old" in case something goes wrong and you need to revert), resets something Cubase-y for the good.
Just type %APPDATA% in the File Explorer or in Run and you'll get there in case you didn't know.
Don't worry about your custom shortcuts to Key Commands. They are magically saved, I guess somewhere else. You can backup them before in the Key Commands section in Cubase, which doesn't load. But hey, maybe it loads without opening a project? Or you can always revert that "*.old" folder and take the key shortcuts file from there!
Cubase runs again. Continue mixing. Bye!
How strange, in my screenshot, the folder I renamed as .old is for Cubase 9 and not 9.5. There's a newly created folder for Cubase 9.5 which is probably the one replacing the buggy 9. Well, if it works...
