There’s a strong case to be made the Rise Of Skywalker was the shit-show it was because Carrie Fisher died. The idea for the trilogy (as little of a plan as there actually was) was for the first film to centre Han, the second to centre Luke, and the third to centre Leia.

Then Fisher died and they had to rework the entire film without any change to the release schedule. And they reanimated her corpse in the most unconvincing and disrespectful way.

I’m not saying the film would have been good - because it probably wouldn’t have been - but I don’t think it would have been the silly, incoherent mess that it actually was. And it’d have been nice for Fisher to be able to give Leia a proper send-off, especially as the character was what catapulted her into stardom in the first place.
