Cannot update to 4.7.1 (from 3.2.2) Error file attached

I tried to copy the error file here and it was flagged as spam. I tried to drag the Garmin_BaseCamp_20200320093119.log file here it does not appear.

I have used Mapsource with a GPSMAP 60CSX for many years. I took advantage of the trade in offer and now have a GPSMAP 64S. I would like to use Basecamp but the Version I have won't update. Any help would be appreciated.
