YT Shorts show “Video unavailable” when enabling YTUHD

[quoctrile8]

Hello, PoomSmart. I got this issue "Video unavailable. Something went wrong" when watching shorts with YTUHD enabled. This happened only with YT Shorts, not the videos.
I also tried removing all the tweaks in YouTube except the YTUHD and installed YTVideoErrorAlert tweak but it didn't show anything when the issue happened.
If I remove the YTUHD tweak, the YT Shorts is working normally.
I attached a screenshot to describe this issue.
My device is iPhone 8, iOS 16.6.1.
YouTube version: 20.04.1.
YTUHD version: 1.5.9.

Hope you can help me solve this issue.
Many thanks!

Can you install YTABConfig, enable it, copy the current settings then send them here?

What happens if you turn off "VP9 for all" ?

It still has that issue when I turn off "VP9 for all".

Strange. It doesn't happen on my devices. Does this occur to every Shorts? Any specific Shorts that this problem occurred on?

No, it occurs in random shorts. Some shorts have this issue before playing, some have it after playing a few seconds.
I can't find any specific info about these shorts.
It randomly occurs in 1080p premium, 1080p60, 1080p, 720p, etc. quality shorts.
Here are some shorts links that have this issue:
