First note that I also got this glitch in 1.20 in the same device.

Weapons like the sword and the new maze don't seem to be affected when enchanted (image 1 and 2). 

Armor, shield, and trident's textures glitch when enchanted (Image 3, 4 and 5)

Enchanted bows become invisible and crossbow's 3D model glitches when enchanted. (Image 6 and 7)

The glitch is also seen when a mob or other player is holding said enchanted items. (2nd video)

The glitch is only visual (as shown in the videos), and other players that aren't glitched don't see it from their own devices. (As an example, I don't get this glitch in my PC, with the same world and account).
