F3 crash when start a connectiq application (APP4TRAIL)

For 2 weeks and for no apparent reason, my application APP4TRAIL crashes very often when I launch it. (black screen immediatly)

It worked perfectly before and I have a lot of users on the store who have no problem except me
I have bluetooth on, as well as garmin connect on my iphone
It works very well for hours, but it's the startup that causes the watch to crash 4 times out of 5

No trace in CIC_log.log except in ERR_log.txt

Is it a firmware or hardware problem on my watch

I noticed that if I stayed for 15 s on the screen of the application before doing START, the application did not crash anymore
Very curious. Loading the VM environment?

With the 15 second wait, could it be something like not having a GPS fix when you think it does? Starting recording when when there's no startLocation, currentLocation, etc? That alone shouldn't crash the watch, but maybe that's a side effect of something else in your code? That also could explain why it just started happening for you, if for some reason it's talking longer to get a GPS lock than it did.

I press START, i wait 15 s on the list of applications of the watch. After 15s i start APP4TRAIL application. It is in my application that I launch the GPS

If i don't wait wait 15 s , if immediatly i start my application APP4TRAIL watch crashes

Does it happen if you reboot the watch and then run your app right away?

The watch crashes, so the watch reboot too. If i wait 15 s, no problem appears

I think it's the vm context
