So the game has never crashed or frozen on me up until now (only some lag, but not enough to really complain about). While doing Diplomatic Immunity, the game froze when I told Delphine I'm ready to take the carriage to the Thalmor Embassy's party. So I put the party clothes on as a disguise, talk to Delphine and once the dialogue is finished the game freezes on me! I can still hear horses trotting and music in the background, but no movement at all. I've attempted changing the graphics settings, window sizes and restarting my computer. It only happens on this specific part, where I have to use the Task Manager to exit the game and run it again. For now, I just put the quest aside and do other things but I really want to finish this quest. I've read somewhere that you can use console commands for these type of problems.. Can someone please help me figure this out?

By the way I'm using a Script Extender and a couple of appearance mods.. I thought maybe they were having an effect on it but I've already tried disabling all mods and running the original Skyrim launcher and it still froze. I'd be grateful for any help.

Fixed!
