Packaged applications will not launch after Win 10 1803->1909 update, can't launch studio

We have found that our library of packaged applications do not work after updating our Windows PC's past 1803.  The applications were mostly packaged on a PC using 1803, when we moved to Windows 10 last year using MFDC-12.3.

When launching a packaged application we get an error that reads:

"The application has encountered an error: The specified path is invalid (0x800700A1)"

When launching the 12.5 or 12.4 Studio:

"Please set registry key HKLM\Software\Microsoft\.NETFramework\InstallRoot to point to the .net framework install location" (I checked, and it does. Reinstalled .net frameworks as well, no avail.)

Is there anything we can do to let our applications launch?  We had to repackage all our applications when we moved to windows 10. Will we have to repackage for every 6-month update of windows? This would be a major headache.
