Lag any time I am in a lobby over 40 players

So this issue only happens on my xbox when I am in a lobby that has more than 40 players in it. To confirm it was a specific issue I played other battle royals and even apex on other systems and it doesn't appear. But about a week ago now after split 2 went live any time I join a lobby that has more than 40 players in it the game gives me packet loss and extreme lag because of it. But my question is what is causing the issue. If it was happening all over the place I could understand, but with there being very specific criteria for it to happen it just confuses me. Does anyone know of a fix or if it is a known issue because it makes the game unplayable until there are less than 40 players.
