I understood you the last time you posted about it.
The problem is that QuickLook is a crappy player, which like old Quicktime requires some additional adjustments which ffmpeg might not be able to do.
You can try if enabling/disabling one of the other options under 'Mp4 Settings' helps with the issue. (I doubt it, but it might be worth a try; especially try the 'Force HEVC tag')

This has nothing to do with Hybrid directly so I will look at it once the basic stuff works.

Not sure how to test other tools but updated x265 render works

call them in a terminal in case they don't throw an error they probably work.

Also please stick with one issue at a time especially if you post them all in this thread.
First thing you should try is the Vapoursynth Preview.
If it reports an error share that error.
