Game crashes when another player joins LAN world

• Playing in a world created in 23w42a and has been updated to 1.18 pre-1
• Game was opened to LAN and there was another player online
• After around an hour the game crashed. My screen froze and minecraft stopped responding and the other player received an error (not sure exactly but sounded like it was about a stack overflow error)
• After logging back on and opening it to LAN again, it crashed within a few minutes of the other player joining, this time the other player didn't get an error message.
• The game is still continuing to crash as soon as another player joins with the same error message showing each time
• World was running fine in singleplayer and in multiplayer there were no noticeable performance issues until it started crashing. 
• attached is the second crash report, they all seem to say similar things
