I want to be clear this is not an issue with gameplay, this is purely an issue with any skin that I use, even when using the Alex skin in the launcher it doesn't load when in game I have looked into this but most answers are either outdated or didn't work, I will send two in game screenshots of before my skins stopped working and after, I do hope this gets resolved, I will continue playing Minecraft but its more enjoyable with customizable creations,

a bit of an update: i also cant play on servers or open my singleplayer world to LAN
