Navigation crash with 1.244.1103

First ride with newly releases 1.244.1103 and the navigation (map view) just "crashed" mid ride during a group ride. Arrow disappeared, map was not updating anymore but speed and sensor data were still updated and recorded. Stopped routing and reloaded track but during ride but that did not fix my problem. Had to blindly follow the other people. Not what I want from a bike computer ...

BTW after finishing the ride the upload buttons to strava, komoot etc. were missing in the save dialog. Had to switch to the routes view to upload from there ...
