I have the same problem

I fixed this by removing the vault from the app and adding it back again.

The error message really needs to be changed to tell the user how to fix it.

Also needed to reauthenticate Cryptomator to get it working again. I removed my OneDrive account in the app and additionally deinstalled Cryptomator. When adding back the OneDrive Account and installing Cryptomator again, it asked for new authentication with the Microsoft account. After entering the vault password, everything worked again.
