"Root changelog for main datastore is missing or invalid"

Hello! From time to time, let’s say 5/7 I receive this message when opening the project. Sometimes restart of PC helps. Right now, again this message. No start is possible. Meanwhile there’s a background task hanging: VCS Initialization. But I don’t know, if VCS hangs because of the error, too, or vice versa. So, currently the project is broken. I have now idea… It worked, when I last left the PC… THanks for your help, best regards HP
