"Multiplayer game" is disabled won't let you enable and cant use default skins

I am not able to enable "multiplayer game" while in my world. It is not the internet nor mobile data both work completely fine. I have edited the world in the menu so "multiplayer game" is enabled but when i load my world it disables it again and it wont let me change it in game. This caused a problem so my friends cant see my world (local play and yes we've tried everything even same connection) When we make a completely new world it still has multiplayer disabled (in game) we tried it on different devices running the same minecraft version happens on all of them. We try inviting each other with Microsoft account but no one can get an invite it doesn't show up (We've all added esxh each other) So there's no way we can play local play. I also get this pop up that if i use a skin it will disable multiplayer but i was using "Steve " and it is strange because it says the skin is compatible cross platform. So i changed skin to another default skin and next time i loaded up minecraft it said to change it again. So no matter what skin i used it still had that pop up. Even when at times it will let me use a skin the it enables me to it still had multiplayer disabled. So I'm assuming this is a bug. Hopefully this can get fixed Thank you for your time!
