Opening level as listen server crashes game

every time I open a level as a listen server it opens it for a split second, crashes to menu, and then if I do anything it crashes to desktop, I’ve tried the following

Isolating the open level node. Does nothing it still crashes, so its nothing to do with the surrounding code

Opening without being in a steam lobby. still doesn’t work

Opening NOT as a listen server, this makes it work and load the level as normal

Opening a listen server in a fresh project. Also works and loads the level as normal

Opening a different level as a listen server. Still crashes

Packaged the game and ran it on several different machines. All crashed

The error code I get when it crashes is as follows

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000001100000038
