Flash band / multiple crashes with newest patch?

GGG when will these crashes be addressed the game is almost unplayable in a party. Still crash solo as well...

To follow up, my guild and I play on PS5 and since the patch a week ago we have all been experiencing client crashes wasting materials and time. It has been discussed on global chat as well, they said co-op play is impossible right now. Wondering if we have to wait until the new league or is this even being looked at please let me know.
