Using Slither Plugin (VSCode) have fixed all error and problems (High,Medium,Low,Informational) now problem Error in workspace

Hello,
I corrected all the errors and problems (high, medium, low, and informational) in my files. So I tried slither again to see if it would say something about no errors which I can show my boss. What I get instead is Error: Error in workspace.... umm how did it work so well for the analysis? and now says this.
How do you fix it? please help!

Start by reproducing the "Error in workspace" message in the Slither VSCode plugin after all reported findings have been corrected. The issue does not name a file, test, workspace configuration, or reproduction steps, so first capture those details; done means identifying the cause and confirming that analysis completes successfully.
