At this stage I am leaning towards a issue with CoreElec, but post your old debug log as detailed above and I will see if I can't spot something.

Leave it with me.
I need a moment of time to do debug on all OS Platforms because the issue happens with LibreELEC Leia as well on my Rock64.
So i've got the issue on all OS Platforms.

I did SMB into CE box when it happened 2 days ago and took logs. 
So until i get time to do the other OS's here are the CE logs.

Estuary Skin has no issues opening favourites on any OS.

@kostaman,

Sorry sport, only error I can see in that log relates to CoreElec update script crashing. Would recommend you update by hand and see if you are still seeing issue. Not saying there is not a problem with favourites in my skin, just no evidence in current log file. Please keep posting logs so that we can pin down exactly what's going on.
