Crash on Fenix 5x without a crash log

I have a watchface that crashes on loading on the Fenix 5X without a crash log.   It works fine in the simulator without errors.  Has anyone else experienced this or know of a possible cause.  It is not a low memory issue as there is plenty of memory left over.

  • Have you updated the firmware on the watch and build the .prg with an older SDK version? I had something similar, once I used the latest SDK and  recompiled the .prg I had no crash.

    I didn't check if I had a crash report tho.
