help! i stuck under the map

we were playing in party with my mate and i teleported to his location, which was literally under the map. i donno how he got there exactly (some bug ofc) but i got there and both our characters were uncontrollable. the character kept falling and standing up very very quickly, i think due to the type of “collision” present under the map. i quit the game then restarted, and i get to continue from the same “area”, from under the map. sometimes you can walk and run on the air but cannot skate there. since there is no fast travel i dont know how i am going to resurface.

in my experience most games detect that you are mistakenly out of bounds, or fallen under the map somehow and they more or less put you back on the map itself at a random location. but here this is clearly missing. basically i softlocked the game it seems.
