Error HRESULT e_fail has been returned from a call to a COM component when double-clicking Package.appxmanifest

[Mike-E-angelo]

Current behavior

Upon double-clicking the Package.appxmanifest file in an Uno project an error is thrown and dialog shown to user:

Expected behavior

No error is thrown and Package.appxmanifest is loaded.

How to reproduce it (as minimally and precisely as possible)

Load this SLN:
https://github.com/DragonSpark/Framework/blob/issues/reported/uno/19066/The%20DragonSpark%20Framework.sln

Then double-click this file in Visual Studio:

Thank you for your efforts out there. 🙏

I have reported this here to Visual Studio:
https://developercommunity.visualstudio.com/t/Error-HRESULT-e_fail-has-been-returned/10819926

Upon searching I found this issue:
https://developercommunity.visualstudio.com/t/Continually-getting-Error-HRESULT-E_FAI/10733627

And this issue:
https://developercommunity.visualstudio.com/t/Double-clicking-on-a-PackageAppxmanifes/10658683

Seems like this is a recurring/common issue with Uno and upon creating a new SLN from the project generator everything works as expected and I am able to view/design the Package.appxmanifest file.

Because of this I am wondering if there is something to do with my framework. 🤔 So, reporting here as well in case there is something Uno-related.

Welp this is weird. In the SLN that was working, now I get an error there, too. Only this time I had the file open and I got a stack trace:
