Vero 4k+ keeps rebooting after april update

After april update 18.2 RC1 my Vero 4K+ keeps rebooting like every 90 minutes and scans my NAS for new content. If the TV is off it also starts the TV since it´s CEC connected.

If I play a movie it´s all fine during the movie, but then again after about 90 minutes it reboots and scans my whole library again.

Any ideas on how to make it stop the restarting?

Do you have a timer enabled?
Can you enable debug logging? Even after the reboot the old Kodi Log should persist

No timer enabled.
Funny thing now that I activated logging it has been stable for 3h… I’ll disable it and see what happens
