Connections problems playing on Epic with more people

I got borderlands 2 on Epic, when It was free, but anytime I play with more people, after a few minutes (can be 5, 10 or even 30); but always, the game freezes sooner or later and It happens always. Could be that related to cross-platform (Steam-Epic)?

Only if I play alone I can play for a few hours without crashing, but eventually It can crash as any other videogame.

Are you experiencing the same or I am the only one?

Not the only one

Yeah, the cross play with Steam and Epic is horribly messy, the SHiFT update basically broke multiplayer if you try to crossplay.
