What happens if you use this commandline?
   ffmpeg -i oHn-.mkv -codec:v libx265 -x265-params

libx265 complains that profile and preset options don't exist:

[libx265 @ 0x55a964637b80] Unknown option: profile.
[libx265 @ 0x55a964637b80] Unknown option: preset.

And I still end up getting the same problem as before

Just glanced over the X265 build documentation and there appear to be 
some limitations in the way applications like ffmpeg use libx265. This 
might be appliccable to this problem. Just tried om my build where both 
libx265 as well as ffmpeg are the newest version and it is impossible to 
set the profile. It remains only on main.



There are two options is you need to use x265, try piping the raw video 
output of ffmpeg through the x265 application. I have no experience with 
this but that should work.
The other option is to use another video codec for example av1 with 
libaom or libsvtav1.
