Friends can’t join my world

No one can join my world. It doesn’t show up in the friends tab and they don’t get my invites.I can join others and my sister who uses the same Xbox doesn’t have this problem on her account, I tried permission setting network and nat type anything I could find but nothing works. I checked to see if I had the same problem on my phone but when I enter a world the multiplayer option is off and when I leave to change it, it says it’s on
