Photos cannot find existing photo library even when I double click on it.
Clicking on Photos gives the message Photos cannot find the System Photo Library named “Photos Library.photoslibrary”
Option-Click Photos -> Create New gives the message Photos cannot find the System Photo Library named “Photos Library 2.photoslibrary” where Photos Library 2 is the name Photos generated.
I have read/write access to the pictures folder and the photoslibrary file. Software is latest versions: MacOS Catalina (10.5.3) and Photos 5.0.
I've rebooted with cmd-option-pr.
Any suggestions what to try next?
