### Summary

Suddenly, I started getting errors when logging in. When I log in, Fortnite opens normally, but after a minute or two, the message “Login Timed Out” appears and I have two options: log back in (if I select it, the same error appears) or cancel, which I click on. Other times, I don’t get this login error, but it still tells me in the top left corner that there’s an error in edit mode. When I return to UEFN and open the log, I see: LogDADUserOptions: Error: Missing expected DAD Creative User Options primary asset:DefaultCosmetics. Make sure the UDAD\_CreativeUserOptions and UPlaylistUserOptionDAD have matching CreativeUserOptionsListName and the UDAD\_CreativeUserOptions is in the primary assets list.
