Tvheadend

I've installed a fresh tvheadend (v4.3-2009~g1295dd2be) instance on a HP Thinclient (Debian Bullseye) for testing purposes.

After all the stuff doing with network, muxes,services and channels I tested the new installation from Kodi with the settings of my old installation. Kodi crashes completely and shuts down whenever I've chosen a channel for playing.

I then enabled debug logging and the last line number always is the same:

There is only one ERROR in the log:

2022-02-16 14:23:59.109 T:22544 ERROR <general>: Got MSGQ_ABORT or MSGO_IS_ERROR return true (-1)

I have several recordings errors like the one below:
2022-02-16 14:22:54.505 T:22422 DEBUG <general>: AddOnLog: pvr.hts: recording id:1843246940, state:scheduled, title:Könnten wir das heute?, error:n/a

I tested several things like modifying the advancedsettings.xml but nothing worked except disabling the "Predictive Tuning"
I've also tested the "feature" with 2 and 6 tuners - always the same behaviour.

The tvheand log looks like this:
