Foreunner 955 solar crash

[MrMojoR]

After upgrading the software of my watch, this datafield crashes the watch when starting an activity two times after that it works fine. Here is the debug log:

There is nothing I can do to fix the issue. The provided log contains the information about a crash that happened in the Forerunner firmware. Are you sure that this data field caused the firmware to crash? Did you tried to start a different activity where this data field was not present?

I would recommend to post the error in the Garmin forums for Forerunner 955: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-955-series

as this seems to be an issue with the firmware. If what you are saying is true, then Garmin needs to fix the firmware so that a CIQ application cannot crash the whole watch.

Thanks, I have checked with multiple activities, I'm sure that this is the one datafield, that crashes the watch. It is really weird, before the last update everything worked flawlessly. I have tried multiple configuration, that is not the issue, even with empty config, the watch crashes. The problem seems to be when the "Network is forming". What is really weird, that the watch crashes 2-3 times immediately after getting to the activity page, but after that everything works.

I have opened a support ticket on Garmin forums: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-955-series/375173/when-using-varia-with-the-smart-bike-light-datafield-the-watch-crashes
