I recently installed Minecraft java edition after a year or 2 witout playing and i didn't had my skin on so i got a new one from NameMC when i joined single player i noticed that i still had steve skin and so i thought that it might be a bug so i made my research on what i could do to fix the bug, turns out i am here so... nothing worked yea '-' i still got my steve skin so i joined a server that i used to play long time ago LoverFella's Server and i asked around if someone could see my skin or if i was a steve turns out they can see my skin but i can't see other people skins and my own i don't know what to do a guy said for me to unistall "Premier Opinion" and another Program starting with the Letter R cause he said that both that programs mess up with the skins but i don't have any of those on my Pc.

P.S- Everytime i create a new world in any version a new skin folder is made in the skin folder that only creates another steve skin even if i select alex on my game i become a steve.
