Visual Studio Enterprise 2017 Version 15.7.4

In Visual Studio Enterprise 2017 Version 15.7.4 Snippet Designer no longer will save snippet and returns error popup dialog:
"The operation could not be completed. Unspecified error".

Found that if I click Save in Visual Studio Enterprise 2017 instead of SaveAll that it works fine. Only if I click SaveAll does it throw this exception. I downloaded the project as a clone and updated the GitHub and compiled the project and installed the SnippetDesigner.vsix from this compile and ran the debugger but it stops at a break point for Save but not the SaveAll so still not sure what the error is, but I will not be clicking SaveAll when I have a snippet open in SnippetDesigner.

I have the same problem with:
Windows 10, Ver 1909 (OS Build 18363.1316), 64 bit
VS Community 2019, Version 16.8.2
Configuration: Active (debug) Platform: Active (AnyCPU)
Downloaded VSIX today (1/24/2021)
Save All causes error to be displayed, Single "Save File" works fine.
