Watchface Crashes, but Sim and Preview are Working

Hi everyone,

I'm having an issue where my generated Watchface is crashing, but both SIM and the WatchfacePreview work like a charm.

Source Code (incl .prg) here:

https://github.com/r-neuschulz/HeartsDesire

Tested on Garmin Epix Pro 2 (Gen 2).

Steps to reproduce:

1. Build the Project
2. Load .prg file to Device
3. Observe how the watchface defaults to a standard watchface, but the preview looks correct (like in the SIM).
