Follow up on issue that CStorms ran into in case anyone else has the same issue.
When the error first occurred, and prior to installing the hotfix, he had chosen the option to suppress Point layout warnings. The hotfix was then install but on relaunch of Revit the APL ribbon did not show up, due to the prior choice to suppress it.
This is easy to fix. From the windows start menu, launch the "Autodesk Point Layout Plugin" app, uncheck the Revit 2020 option and press okay. Relaunch the app again and check the Revit 2020, and hit okay. The ribbon will now reappear in Revit 2020 and all should work as intended.
