ERROR- CE-34878-0 [PS4]

I am reporting an error that occurred in The Lost City of Amdapor (Hard)

Around the areas, X 11.2 Y 9.4 and X 11.0 Y 12.0 when the Rift Dragon (LVL 60) appears and the group brings it's HP down to like 50 or 40%, my game suddenly crashes and the PS4 would say "an error CE-34878-0 has occurred". I would either crash once or twice at that location in the Lost City of Amdapor (Hard)

This has been going on since patch 3.2 was released; I never had any issues with my game crashing until now.

My internet had 100% connection, so it can't be my Wi-fi.

This has just started happening on our PS4 after 3.22 in Idylshire
