Which Xbox console are you using? =OG Xbox
When does the crash occur? (On launching the game, whilst matchmaking, whilst in the game, other (please specify)) - It's mainly only when playing duo or squads now since the latest update, most of the time it's after landing on the island within the first 3 minutes of the game.
What happens when you crash? Is there an error code, does it kick you to the dashboard, or do you go back to the main menu? - No error code, sometimes I get the fatal error occurred but normally it's a return to the dashboard and reload the game, I do get the option of re-joining game in progress though.
