cannot run simulator with Instinct2X

When trying to run to run any of my apps ("Nap till rested", "Body Accounting", "Battery Guesstimate") with the newest SDK (4.2.4) and the new Instinct2X watch in the simulator I get this error:

Clicking on "continue" produces more errors and finally a simulator that does show the watch but does not start the apps.

Is that a bug in the simulator?

I'm using VSCode on Ubuntu Linux
