The budget for Galaxys Edge was cut by Chapek, it was only part of what was planned and what did get implemented was often less than originally planned.

Other than cutting the budget, I think were they went wrong with it was making too high a concept for a theme park and centering it around the less popular sequel franchise time line. It made for a confusing experience for a more casual Star Wars fan.

I stand by RotR being an S tier ride, when it isnt operating broken, because its over complicated and the maintenance budgets were cut.
