In step 4 of the CpsExtension it mentions the following:

Once the nuget package was added to the project, you should notice a new debugger named Custom Debugger on the main tool bar on the start button.

After fixing the attributes in CustomDebugger by applying the fix from #356 the CustomDebugger class gets constructed, but none of its methods are ever invoked. It also doesn't show up on the start button of the main tool bar.

Tested in VS2019 and VS2022 (using Microsoft.VSSDK.BuildTools version 17.2.2186 instead of 15.8.3247 for VS2022).
