Using ActionMenu in ViewLoop crashes and reboots watch

Trying to display an ActionMenu using WatchUi.showActionMenu while a ViewLoop is active immediately hard crashes my device (i.e. it reboots). It works fine in the simulator.

This crash has also been reported by another user, see the first comment here:  forums.garmin.com/.../viewloop-question

• Device: Fenix 6S Pro
• Firmware: 25.00 and 26.00

I just verified this on the newest firmware 26.00, the error log (GARMIN/Debug/err_log.bak) contains the following information after the watch has crashed and rebooted:
