6.5.2 Freezes in the 'Upgrading Database from v22 to v23' Phase

I have tried three times to load 6.5.2 and every time the load loading process freezes at the point when Tribler “Upgrades” from the v22 database to the v23 database. There is no error log that I can find in the Tribler program file. I have left it to try and do its thing for several hours, with no success. Anyone have any ideas how to get past this?
