OSMC crash and restarts endlessly

Dear all,

I am experiencing a new problem since 2 weeks, which might be related to the Isengart upgrade (currently on 15.1 RC).
Since then I cannot reboot the Pi anymore or it will start up and go in an endless Kodi start, sad face, restart loop.
After browsing through the logs, looking for something that leads me to the cause, I found a workaround.

I had to manually edit guisettings.xml set “`false” and poweroff the Pi. It is NOT enough to just “sudo reboot”. When i coldboot the Pi, OSMC will start w/o PVR manager which I then can enable again in the settings dialoge.
Once I reboot the Pi again, we have the same problem again. The logs don’t show me any signs of the cause.
As Kodi restarts very quickly in an endless loop, it is kinda difficult to make a copy of the log files before they are overwritten.

The logs can be found here:

Thank you!
