Test run freezes

I’ve designed a watch face which displays the time in words. Like when it’s 7:00 AM it dispays “seven o’clock” (But it is in french, whatever).

Everything seems to work fine when I run it in Galaxy Watch Studio but when I push it on my galaxy watch active 2 with “run on device”, the watch face is just a still image of 10:08 “dix heures huit” and it won’t change at all.

I really don’t know how to fix that, maybe someone has encounter a similar problem and know de solution ?

Seems like you have a memory issue or one of your bitmap fonts is not right.
For the first issue , reboot and hold down to the button to clear the cache memory
For the second one thoroughly check all your bitmap fonts
