Rush clubs not working

I’m trying to play rush with two of my friends and it keeps giving us failed to matchmake no team mates found. Two of us are on Xbox series x and the other on ps5. When the two Xbox users play we can find games but when we add our mate on ps5 it doesn’t ever find a game is there something we can do to fix this or what’s the issue? We’re able to play league games and everything else but rush giving us these headaches.
