"Failed to connect with database"

"Failed to connect with database
/Volumes/Photos/DT photos/2020/202001/202001.cosessiondb

Database connection FAILED

The requested document type is not recognized.
The provided database is of an unknown type."

Today when trying to load this session I'm getting this error message? Any ideas what's causing this?

    No idea, but have you tried to verify and repair the database (File menu, Verify)?

    That’s also the message I get if I try to verify. I’ve restarted the MacBook and still getting the same message.

    Is it just the on session that is a problem or are all sessions the same?

    Are there many images in the session?

    Was it created as a C1 V20 session or converted form an earlier version?

    If you can not repair the session database (a.k.a. the session file), you could search the web for an article with instructions. Search for 'fix a corrupt session file'.

    Are there many images in the session? Around 100

    Was it created as a C1 V20 session or converted form an earlier version? C1 V20

    Thank you. There is a specific post on this though I am unable to create a hyperlink.

    https://support.captureone.com/hc/en-us/articles/360002418977-How-to-replace-a-corrupted-broken-session-

    which has been most useful if anyone else runs into the same problem.

    Hello datz,

    The automatic hyperlink functionality has been disabled in the forum to discourage spam posting with hidden links.

    Hopefully users can either copy and paste the posted link into their browser or perhaps highlight the link and right click to launch a tab/window to view the link.

    It' certainly still worth posting these useful links!
