HereLink switched to fastboot in flight

We had an issue today where our HereLink “changed” to fast boot during the flight and the SBUS output did freeze in a non neutral position.

There was no possibility to make any input until a full reboot was performed (by pressing the power button for 30 - 60? seconds).

I wonder if the unit is faulty and if someone could have a look at the logs. I would like to send the log via pm but are very happy to discuss the analysis here. I think it might be probably interesting for HereLink users.
