I just created a video of it. This is also already reported in the bug list of Toengel. It happens in Tagesschau app more often, but also in other situations.
After the restart, the TV shows the box, that a channel update will be applied after next standby. The cable provider (KabelBW) stated, that they only provide channel updates at 3:00 to 5:00am in the morning. so it does not get one at the time I recorded the video.
Hopefully this helps with investigation...
It is not deterministic, so it might happen after the first video or later ... Even when the videos are still the same.
Updated to version 000.140.047.000 some months ago - it still crashes randomly
