Main company library shows file size but once clicked on is blank all of a sudden

Seafile server pro 7.0.10. All of a sudden today about two hours ago. Our main library (we have many) it shows it’s file size. However, once you click on it, it is just a blank screen. All of the other libraries are fine.

I am the owner of all libraries and I also get the blank screen both internally and externally. Any thoughts?

This is a big problem

server has been stopped and restarted still same white screen on main library

if I go into history settings I see a message that the library cannot be found?

Also I can see the library folder in seafile-data/storage. Can anyone help with this?
