Unable to open files
I updated to Catalina 10.15.1 last night.
This morning I cannot open files using Numbers, Pages or Keynote. Message simply states " The document "XXX" could not be opened".
When I go to the file on yesterday's Time Machine. the file can be opened.
When I bring the copied file back once again it cannot be opened.
