I have tried all of the suggested fixes multiple times.  None have worked.  Please note that late in 2019 (after I had already loaded PS 2019) my machine was updated from Win 7 Pro to Win 10 Pro.  It was one of the very last Win 7 machines that Dell sold.  I requested Win 7 Pro when it was purchased, since we liked it so much and all of our other machines were Win 7 Pro at that time.  Can ProSeries Tech support help me?!?!?
