Forcing people into my games?

my gf and i have been playing this game for a few hours now, and out of no where, it started adding random people to our party. at one point it even said we had 8 people (which skate only allows 4 in a party?)  it kept forcing people into our lines and sessions. then we wouldn’t be able to finish what we were doing because not all players could trick on the spot. it keeps doing this, and then (if we somehow) miraculously finish the line, it glitched us out of the game. photos added! we are on playstation 5
