Destiny 2 shipped with an issue where attempting to swap equipped gear at specific points during the loading process ran the risk of items being irrevocably lost; to prevent this from occurring the game boots you from your menu just before these load points occur, potentially doing so multiple times in a row if you keep reopening your menu. It would likely be less annoying if the game booted you once and simply locked you out from opening your menu at all until the final problematic loading point had passed (static loading screens with zero menu interaction available is the industry standard, after all), however the current system at least allows the player to access the menu to return to character selection if they happen to get caught in an infinite flight loop rather than having to force quit at the system level.
