same error for me. Projects won't open

I had been working on this issue and thought it was fixed. If you can provide me with a solution (with its projects and files) where it happens, I could try to reproduce and resolve it...

Sure thing. By the way, mine displays a different id but same error message in general. Also, none of the projects will expand when clicked on like normal and I have other solutions with multiple projects that open just fine. I'll reply here with the solution in a zip when I can. Thanks!
