Photoshop CC 2019: Error message 'Could not complete your request because of a program error'

I get the above message when trying to open Photoshop CC 2019.  This is what I can see in the PSerrorLog.txt folder and really not sure what to do to put it right.  Any advice or ideas would be appreciated.
Thank you.
