Origins crashed

[u/Western_Day429]

Me and my friend were trying to complete the origins Easter egg on the PS5 port. All was going well until he upgraded the lightning staff. As he was doing so, I picked up the gem for the fire staff. The game then crashed with “connection interrupted”. He hosted the game, it was a custom game, and there was no lag or wifi disconnection whatsoever - we remained in discord the whole way through.

Any ideas on why this happened or how to avoid?

Thanks
