This is an issue of your system having problems handling the files. The files are fine.

I'm using Windows 10, version 1909, build: 18363.836.
Here only mkv files do not show thumbnails and the only thing I did was install  'HEVC Video Extension from Device Manufacturer' like mentioned in the link I posted.
For mkv files to work Windows needs a special splitter.
Since I do not plan to install anything to support thumbnails in mkv on my system I can not really help you with that.
I thought the Icaros Shell Extensions would help with mkv files, if it doesn't I have no clue.

That fixed mp4(H.265) thumbnail creation on my Windows 10 64bit system (no Icaros).

But it doesn't really concern me much since I don't use the thumbnail view.
Might be some feature x265 supports but the H.265 decoder in Windows does not support, might be some change in mkvmerge or mkvtoolnix.
I have no clue and I'm probably the wrong person to ask.
You might have better luck asking folks over at videohelp.com or a similar board.

1. I don't know for sure that older x265 can fix the issue. Might also be something in mkvtoolnix, or an old mkv splitter. Even if this was caused by a newer x265 version, since x265 normally only fixes bugs and should be H.265 standard conform this should be fixed in the splitter/decoder used. Since the same video stream works fine when wrapped in an mp4/ts/m2ts container, I doubt it's x265s fault. More likely a bug in the splitter or simply an old splitter.
   
2. I also will not start adding different versions of tools to Hybrid. Since Hybrid is way too large as it is.

No it does not.
If you got a decent HEVC Decoder that Windows Explorer uses, like the one from the 'HEVC Video Extension from Device Manufacturer', Windows Explorer ahas no problem to create thumbnails for x265 inside .mp4.
The main point you seem to be missing is that this is not Hybrids or x265s fault, but more like a missing feature in Windows 10.
Microsoft removed the (beta) HEVC decoder which came with Windows 10 in the beginning and converted it into a pay version which it called 'HEVC Video Extensions'. Microsoft removing the decoder 'broke' the creation of H.265 inside a mp4 container that is neither the fault of x265 nor Hybrid.

The only problem I see is that the Windows Explorer can't create thumbnails for H.265 files inside an .mkv container. Which at least here it never could.
From what I know read in example here Icaros should be able to allow the creation of thumbnails for mkv(h.265) files assuming it is configured properly. If that does not work for you you might want to ask the Icaros developers for help over in their forum.
