All my scores gone

Today I was using Musescore 4 and my screen suddenly turned black. This has happened ever since I started using Musescore 4 and every time it happens it asks if I should restore the last session so I didn't panic. After the black screen was over, I opened musescore and waited for the "Restore session?" statement. It never came and then I saw that all my other score saved to the cloud were gone. I've spent the last few hours trying to restore them somehow and I've only got a few ones restored and saved to my computer.

Is there any chance that Musescore can go to their cloud and restore the scores for me?
