Catalina has lost my Photos and Library Repair fails
Upgraded to Catalina today and when I went to open Photos a dialogue box came up that says "Photos cannot find the system photo library named " .... ".
When I attempted repair the library repair failed at 0%.
I can't turn on Photos in iCloud to bring the photos down from iCloud because if I try to put a tick in the Photos box in iCloud (System Preferences>Apple ID) it won't allow it and just says "Checking Library".
Any ideas on how to get my Photo library back would be most appreciated.
