Game crashes after swapping account at start of the match

This has been in the game for ages, but I haven’t cared enough to report it, but sometimes if I forget about it I get banned like 2 minutes ago so I thought I should make a post. I’m on new gen xbox and if I play on one account then swap xbox account to my brothers then load up the game and he starts a q or vice versa, it will all be normal until the second the clock hits 0.0 as the round starts the game crashes every time I can remember without fail, going into a custom or practice range doesn’t seem to mitigate it, the only thing that does is going into a quick match and having my game crash then going to comp after. This has been in the game since at least ow2 season 5.

Last night he was on and today I loaded up went into a custom for primal mechanics for 15mins then went into a 6v6 game and it crashed.

Oh yeah, also at round 3 and 4 in 6v6 comp you don’t get perk progress complete
