not sure how to fix this; been searching for an answer, and possibly might have something to do with a missing package but i cant tell what the **** the package is here so yeah

tried directly downloading KB4574727 and installing it that way but it didn't work either

tried multiple easy fixes and whatnot? i don't know what to do nothing is working and im dumb as ****

asked a friend as well and they had the same problem with this specific update
