Latest Patch Black Screen with GUI still showing after teleport

At least for me this issue used to occur without the black screen, but with the latest Patch Black Screen with GUI still showing when I teleport to a crowded location, it doesn’t come back it just hangs like this. Sometimes I can exit to character select, and sometimes it just crashes but the report in the Fenris log shows up the same in either case.
