    To reproduce:
    - Create a new Core 3d project
    - Create a new C# script, called anything you like, e.g. foo.cs
    - Wait for that to compile
    - Go to 'game' tab, click on 'free aspect', select 'vsync'
    - command-s to 'save'
    - Quit the project
    - Start the project
    - Press 'play' to play the project
    - Double-click foo.cs, to open in Visual Studio Code
    - Add a space, or modify foo.cs in some way
    - Save foo.cs
    - Alt-tab back to the project
    => spinny, and crashes

    By the way, this was a pita for several weeks. Then I spent ~3 hours figuring out what the root cause was. Yeah, that was not easy....
