The only option left is to kill the Visual Studio process in Task Manager. This error completely freezes the Visual Studio UI. When I run the project under VS2017 debugger, it fails with error: TypeError: is not JSON serializable Without the Visual Studio debugger the application just runs fine. I have to implement minor changes in it therefore I would like to debug it in Visual Studio 2017. I have a legacy console application written in Python 2.7.
