Not sure if this is a bug or a setting I have turned on, but the game launches with this as my skin no matter what I change it to in the MC launcher. Anyone know a fix? (Stoneblock 4)

Launched from Curseforge and didn't change any files or anything, just always stays as this mc default skin. Didn't happen when I first started the pack where my skin loaded just fine, started around 10-15 hours in
