Crash when hosting

[Zuurick]

I will give as many details as possible about my issue. Any help on a potential fix would be greatful. I play on PC. I have currently been playing with my brother (PS5) and my cousin (PS5). Initially i just thought this was a crossplay issue as I had very few crashes/disconnects before I started grouping with them. When it is just my brother and I, when he hosts the lobby he cannot call in and SOS beacons so we end up playing as a duo every game. Also we still crash somewhat often. When I host other players can join and I can call in SOS, but when i host it is every match I or we disconnect sometimes within 1-2 minutes. Sometimes we dont get seperated or kicked for half an hour. Which is about the max time before the kick. When my cousin hosts we can play an entire night with little to no disconnects from the party. I did not notice this til last night when he hosted. After my cousin logged out we started having the same issues we had been having. This has been going on for three days now. I know the simpliest soulution is to just have my cousin host, but he plays the least out of the 3 of us. Any help would be greatly appreciated. I just want to play the game.
