Recent projects empty and project bloc disappeared

Last night got an upgrade for Catalina, Mac Mini restarted and now I only have the last project I worked on in my recent project list. Went looking for the other project files (.bloc) for a website I am building and they have disappeared… Used all the search possibilities but to no avail. Anybody out there have a tip or suggestion?

Because I did not have time machine running I do not have a backup for the last few days, stupid. Is there a way to import a Bloc site in to Blocs without having the bloc project file?
