Sounds like the common Nvidia white/black screen error others have been posting about, seems to be hanging up on the intro into Midnight. DX12 was made minimum with prepatch, but you can try forcing the client to use DX11 by adding the game settings. -d311 I believe.
For me, it evelentually crashes back to character select with the “Character Not Found” error. This only happens with characters in a specific guild. My guidless characters get in fine.
