Kodi is disappointing me. help!!

Hello, I always used Kodi to watch films as in HD as in 4K.
Kodi has always given me great satisfaction. But now it is disappointing me.
In fact I have I have just made a video in 4K and Kodi reads well almost all the video but at a certain point it seems
go crazy for 20 seconds. Look here:

I whatched tha video with another software that is inside my TV Sony Bravia 65 “
it reads that video without problems. But I need Kodi.
I am so demoralized!!!
In fact before using Kodi I tried various programs but no program
gives me the chance to line up the entire list of
my movies I have in a folder. For me it is very important.
What can I do? I have Kodi version 16.1 and it seems to be the latest.
Is there another kind of Kodi or every Kodi is the same to other?
Thanks for some suggestions that might cheer me up.
