If your on a console reload a save if you can before entering the gate of before first approaching the Sigil, if you on a PC you could try the command (from inside the gates realm) -

CloseCurrentOblivionGate

It might be caused by loading a save thats inside a gate without fully quitting the game (but not sure).
