The main problem that Disney faced was that it could not explore the immediate years after the second Death Star in the main trilogy. Every actor that did the original trilogy was basically at his 60s/70s.
So it kinda kills half of the EU where we got the new Jedi order with Luke, Mara Jade, Thrall, Rogue Squadron, Ben Skywalker, Jacen/Caedus, Chewbacca's death etc.
They need to go directly to 30 years after DE2 or no nostalgia driven box office for 7-10. Everything felt disjointed....
Then, after all this... They let a lunatic, with absolutely no regard for the canon, loose to take charge of the most important episode of the new trilogy. EP.7 was salvageable, EP.8 was not, especially after Carrie's death, Hans death, and the complete disregard of Luke's + his death.
The premise that the empire was back while the New republic failed isn't the problem. The problem is EP8 imploding 7 movies of lore and canonicity because "LOLZ I'm the vanguardist Ozymandias director of Breaking Bad"
Disney ain't going to cancel the new trilogy with another trilogy focusing on Rey on the oven. The only solution IMHO, as I said, is to make a 10-13 trilogy imploding everything that the 7-9 created. Or pull out narrative device on the series, Andor/Mandalorian etc that introduce the "time traveling/multiverse" right before the beginning of Rey's trilogy, but that cannot be done without imploding the box office of the current in preproduction 10-13 trilogy.
We're going to wait a long time to see the universe going forward.
