Tvheadend HTSP client addon causes boot loop when kodi language changes

  • What is the problem & how to replicate: Fresh default libreelec installation, install tvheadend service (front end), change kodi language to Greek. Reboot, system works fine.

    Now, install tvheadend CLIENT addon provided in libreelec repository, reboot, system does NOT boot up, its stuck for ever in a loop.

    It seems this is a known problem for quite a few months now, there are for example posts in kodi forum and tvheadend support forum, seems related to language or EPG. Missing translation parts?

    Apparently not fixed yet, so here is my question: I was wondering if there is a "trick" to switch to Greek in entire kodi interface, BUT, keep using English in the affected part (HTSP client?)

    Maybe copy parts from english-language-files into the Greek version files? No idea where to start, any help would be welcome

    PS: Not helping much, but, here it is

    The last part of crash log, no warnings no errors whatsoever in logs

    end log = kodi restarts....
