Issue w/ going down after opening SAM trial chest

Hey guys, I’m currently experiencing an issue when my husband and I play COD Zombies together. We play on a PS5 and use split screen for context. We’ve run into this issue playing both with just us, as well as with a squad. Frequently after we’ve completed a SAM trial, we’ll go to unlock the chest to claim prizes and our screen will completely freeze up. We can’t move, (very slightly at least), can’t shoot, and almost immediately go down. Even after being revived by another player, the glitch remains and we’re unable to get back up. The only way we’ve found to stop this is by fully dying, but this is usually happening 25+ rounds in when we’ve gained double pack-a-punches, perks, etc. and it’s extremely frustrating. If anyone has experienced this or knows any solutions or what the issue may be, any advice would be appreciated. Thanks! Oh also, the same issue happened just today when my husband went to buy a boat to reach the islands during a Terminus round. It only happened to him, but froze both of us due to split screen. So I’m not really sure what triggers it, and we’ve had rounds where we’re able to collect prizes from the SAM chests with no issue so it’s pretty spontaneous (which makes it 100x more frustrating.)
