I believe my friends and I experienced something similar last night. I'm hosting on PS5. One friend on PS5, another on PC. We live in separate areas but didn't have issues one week ago. New hotfix installed, and now as the host, it intermittently gives me "online features disabled" errors and boots both friends out. They're unable to join back, and my Larian account is inactive until I restart the game. Happened about five or six times, one game without any mods at all just to test, and then five times with mods. We usually were booted within a minute or so, but once it went about 15-20 after I restarted my PS5. Hope they fix this. Very frustrating. We couldn't even really make progress except for that one long window.
