    Right-clicking in the Project window provides the ability to "Open" always. Clicking the "Open" context-menu button, while no asset is selected, displays an ArgumentOutOfRangeException.

    Exception thrown while invoking [OnOpenAssetAttribute] method 'Unity.CodeEditor.CodeEditor:OnOpenAsset (int,int,int)'
    
ArgumentOutOfRangeException: startIndex cannot be larger than length of string.



    Reproduce
    • Open attached project or create a new one
    • Right-click in the Project window while no asset is selected
    • Choose "Open" from the context-menu

    Actual
    Unity outputs an ArgumentOutOfRangeException exception.

    Expected
    The "Open" button should be disabled if there is no selection.

    workaround:-
    open Preferences, to External Tools and reselect Visual Studio from the dropdown menu, it should resolve the problem.

    Had the same error and this worked:
    Exit the unity, delete all auto-generated csproj and sln files from the root folder of the game, open the project again and generate them thru Preferences->External Tools->Regenerate project files.
