One reason I can think of, is that Andor is firmly aimed at an adult audience, sure its not deliberately kid excluding by including graphic sex scenes or ultra violence or prolific swearing to get a high age rating, but thematically it is.

Studios are obsessed with hitting as many quadrants of potential viewers as possible, removing kids from the equation hurts their potential bottom line. Andor being successful leads to the demand both in and outside the studio to make more content like it, which will impact potential revenue.

Star Wars should be chasing $2bn per film in the Studios eyes due to the amount invested into buying and operating the franchise. That leads to them trying to squash stuff that wont hit those numbers if its going to take up valuable production budgets and release schedule slots.
