Cant join a crew as a crew member

I'm trying to join my friends crew as a crew member on one of my characters. My friend says when he tries to invite me it says "This character can not be invited"
I tried to click on the all 4 one menu and it says "You've already been invited to a crew on another character" Yet I wasnt.
I'm thinking it has something to do with how my main is already a crew boss, however there are no crew members to that crew yet.
Is this the problem and if it is, how do I get out of my crew as the crew boss so i can become a crew member on a different character?
I dont really know what is causing this problem for sure.
