Horse texture glitch

Horse texture has gone crazy, I reinstalled the game for 1 week now, and I didn't spend much time playing on my phone, so I never met a horse in the game before (on my phone). I don't know what happened, but this "thing" can't be made using a behavior pack or resources pack. (I'm using Vanilla resource pack)

What I've tried:

• Close the game and relaunch.
• Restart my phone.
• Clear all data stored.
• Reinstall the game.
• Go offline/online.

Only affect horse texture, not behavior, other mobs are normal.

Uncut video download from store and run the game with network connected: https://www.dropbox.com/s/o26v3loxygvxmb4/20220518_092610.mp4?dl=0
