Sorry for delay
I have some progress. Epg is loaded, kind of start recording. json file created with name of recorded program. ts file created but 0 bytes size as recording endings after few seconde.
Are you polish by any chance? I have spotted something could suggest so :
   

I'm not Polish. Someone probably forked a copy of my code. Quite a few Polish people have asked questions about my addons.

If it creates a ts file it means that ffmpeg must have started but failed.

Turn on
Settings \ Debug \ ffmpeg stdout/stderr
Then try to record something else.
Look in
userdata\addon_data\plugin.video.iptv.recorder\jobs
for the stdout and stderr files.
They should tell you where ffmpeg failed.

Turn the debug setting back off again to record properly.  

To be absolutely sure I have just downloaded newest version of ffmpeg.exe
so now I have this in my log file https://paste.kodi.tv/ufomizijok.kodi 

You haven't set the location of ffmpeg correctly or the permissions are wrong.
Also start with Record Once from within IPTV Recorder. It looks like you started in the Channels menu of the Kodi PVR.
