Minecraft skin stuck on default Ede skin

I have been facing this issue since I brought the game i brought it in the 15 anniversary sale I've been playing on the 1.20 version for a while every time I change skin the skin changes in the launcher but when I load my Minecraft world the skin is stuck on default Efe skin I ve even tried changing skin from the official Minecraft skin changer website but still it is stuck on Efe skin I have not even installed any mods I'm only playing the vanilla version of the game .
