Skyrim Crashes 1min after starting

[MrDuck]

I have multiple mods and have gone through the whole campaign....but right as I join the war on the Imperial's side, my game keeps crashing.

I deleted most of my saves in case it was due to not having enough space but it still crashes.

I'm not sure if its due to the time period i'm at in the game or just all of the mods I have are screwing up the game.

Please help me!!
