Game crashes with spawning boomer

[midnight badge]

So, I've met somebody I'm this discord and every time when I join his game some weird stuff happening..
I've had it multiple times that I don't know/see what he's doing, goes down, I try to revive him and as soon I touch the ground, a boomer spawns , kills me , and I get a blackscreen..🤔
we both on ps5.
He doesn't say/show what he's doing so , it kinda makes suspicious 🤷 ..
