Detailed repro steps so we can see the same problem

1. Open PM UI for project

2. Right click on tab header
   

3. Select "Open file location"

Result: error message

btw, if you do the same with PM UI for solution, it opens file explorer in solution file location.

If you select "Copy Full Path", then paste it, it actually contains the relative path that's in the .sln file, which is probably why opening the folder fails.
