Unable to open June 2020 edition of Power BI Desktop. We weren't able to connect to the model.

Before reviewing my error message and details, please note that I have tried everything suggested in the community blog, Power BI blog, and Microsoft Documentation for this error - including but not limited to: reinstalling the gateway, removing the gateway, removing all traces of SSAS tools, removing SSMS, uninstalling 64 bit edition and trying 32 bit edition.  I have never encountered a problem upgrading to a new edition of Power BI.  This is the first time that I have encountered this problem.  I know that this has been posted in the past, but there does not seem to be a clear line of resolution.  At least that I have found.

Thanks.
