I keep getting a "Device is not set" crash

This one is getting annoying. 

I previously changed the launch.json in accordance with forums.garmin.com/.../vs-code---start-debugging---device-selection

I am trying to learn how to do menu2. I created a basic watch face with options (straight from VS).  I then tried to add a toggle menu option (Jim, your ComplexWF is helpful, but the shorthand and multiple items make it a bit..Complex (haha)).  I can get the app to execute up until the simulator opens and I get a "Device not set" crash error. I only have 1 device as an option.  Usually, when I execute my apps to test, it asks me for the device I want to test.  It is not doing it, just crashing.

Any help?

Thanks
