You forgot to factor out the alpha correctly at 4:42. There should be no alpha inside the parentheses to apply the parallel axis theorem :) Also, and I am not sure, but I think you flipped the tangential and normal reactions at 9:00. The normal reaction should point to the center of curvature. Thank you for the video!

This Video is very helpful Sir. Thank You very much.
Well explained 👏
