An unexpected disconnection occured - issue when entering endgame maps (Xbox Series S)

Hello,

Since few hours every 2nd-3rd map in endgame atlas is a "bugged" map - when trying to enter it kicks me to main menu and I'm getting error "An unexpected error occured". Nothing like restarting xbox doesn't help. I need to put another waystone and hope the next map is not bugged. Especially infuriating because it's wasting special events on maps.
I'm playing on Xbox Series S

All good after new patch
