In watch mode or during an activity? IQ! errors can occur when a data field or watchface is a CIQ app and needs updating to work with the new CIQ version.
I have the same problem, but only with the Stryd data field. I tried resetting the watch to factory settings and reinstalling the data field via Garmin Express, the result is the same. I only have one data field from Garmin IQ, no other data fields or applications from Garmin IQ are installed on the watch. On firmware 19.18 everything was fine, after switching to firmware 20.26 and 20.29 this problem appeared. I wrote to Stryd support, while this issue is being studied. Currently, the problem is relevant.
