Armour model and texture bugging

I gradually loaded an old world (created in 1.19) to 1.20.30,

I had enchanted diamond armour on before upgrading to 1.20.30, after loading the world, my armour turned into bugged textured and modelled. However, if I take that specific armour off (The one I left on) and wear a new set, it does not bug. It never happened before 1.20.30
