Listen, director Rian Johnson could have easily taken over the director's chair for Episode IX, but Disney decided otherwise. They opted for JJ Abrams, who was the brainchild behind this trilogy and probably saw Johnson starting to interfere too much with his original vision of the way things should be going in the story. Johnson's risk-taking was a breath of fresh air, but I never doubted that we'd be going back to business as usual with Abrams hopping on-board Episode IX. It had to go back to normality, especially after the backlash from longtime fans due to what Johnson concocted in "The Last Jedi." It made $300M less than Abrams' "The Force Awakens," which is probably due to hardcores not going to see it a second or third time in theaters, like they normally would with any other Star Wars movie, because, well, they were not happy with what they say the first time around.
As perVariety, it seems like a 'course correction' is most definitely happening for the final chapter:
"Disney, one party wages, is in the pole position since the company has a strong foothold with Abrams thanks to his work in the “Star Wars” universe as a writer, executive producer, and director. He’s currently working on “Star Wars: Episode IX,” which has been billed as a course correction at Lucasfilm after spinoff films like “Solo” failed to meet the label’s high commercial expectations. He enjoys a close relationship with Iger."
