Well, I uninstalled Skyrim and reinstalled my mods and everything else, but the error persisted, so I uninstalled each mod until I got the 'Ultimate Combat' mod, I uninstalled it, and it worked, the bug stopped, but I was dissatisfied, because I did not find anyone else with that same error, ie the error was some problem of my Skyrim only, but in short what I did was clean the mod with TES5Edit, it seems that after that I can use the Ultimate Combat without error, maybe some wrong script or something like that corrupted the game, but now it's all right, and I just wanted to share this with those who are also behind this error and need help to fix it, remembering, I used TES5Edit to clean Ultimate Combat.

UltSky is intended for players who enjoy dynamic fantasy worlds with deep mechanics and systems. I searched a lot and did not find answers that would give me the real solution, and to tell you the truth I do not think there is a definitive solution, but I managed to fix it and now I'm going to share here what I did to fix it. Ultimate Skyrim is a survival roleplaying modpack for Skyrim.Its goal is to transform Skyrim into the ultimate fantasy life simulator by combining the excellent mods of the Skyrim modding community with proprietary features found only in Ultimate Skyrim.

So I was playing with the Alternate State mod, and I chose to start a new life at Lord Harkon's court, the problem is that shortly after I became a vampire lord, I could not use my magic powers, hand, I could only go down and use my claws.
