Cannot Restore Photos Library From Backup
When attempting to restore a Photos library from a Time Machine backup, the restoration sticks in "Preparing to copy". I've let this run overnight and it still didn't restore. The backup was done in Big Sur. I recently reverted back to Catalina (to install Boot Camp). I have now re upgraded to Big Sur and receive a message saying "Photos was unable to open the library" when opening photos. I'm hoping the Time Machine backup library will open but I can't get it restored.
