After going through the Temple of Miraak and entering the final room, I am unable to learn the shout, so none of the casket breaking animations happen and I can only stand around awkwardly.

I'm not sure if this is because I already learned the first word of "Dragon Aspect" From Zahkriisos' Lair, and that wall is programmed to have me learn solely the first word.

When I look at the shout to learn it, the blue swirls just go around me endlessly. I have tried reloading a save, and that resulted in no difference.

I have quite a few mods installed, but I can't think of a reason they would interfere, the only mod i have installed that affects Dragonborn directly is Unofficial Dragonborn Patch.
