A new Visual Studio (version 2017) issue started recently that prevents me from opening ANY files using the File -> Open -> File menu item (or its shortcut Ctrl + O).
Error message from Visual Studio:
There are plenty of posts on various web sites including Stack Overflow that deal with not being able to open file related to a solution, like deleting the .sou files. The discussion forums at Microsoft are basically useless with answers stating that they cannot reproduce the error, so it's not a bug. None of the help pages that I have read online has helped at all. This is not a problem with any particular VS solution or project. I cannot open any file even when there are no projects open.
