In the first attached video is my view, on my screen it's as if my friend had a sheet of metal in his hands, but in his game he has NOTHING in his hands, resulting in the video bug.

In the second video is my friend's vision, in his vision I have the animations completely broken, with nothing in my hand, he doesn't hear my steps or my shots, because in my game I have a blaze in my hands and I even shoot killing the dead player on the ground at the end of the video.

I play on Xbox one X, my friend on Xbox Serie X, demonstrating that it's not a hardware problem. DayZ 1.19.155542
