I'm having a strange problem on my development workstation. I can no longer publish ANY single customization package within Acumatica using the Project Browser window. But strangely, I can still publish ALL packages without issue from the main Customization Project screen (SM204505). This makes for an awkward development workflow.
This behavior started after I upgraded Visual Studio between minor versions: 15.9.17 to 15.9.28.
Here's a screenshot of the error in the Project Browser:
The 505 error trace log in Event Viewer:

I'm not sure what to try to resolve this. Any ideas?
