Routes removed in 10.4 and not 11

Working on it.

I have applied the patch you provided and checked according to the steps you provided to reproduce and there are no PHP errors on the Structure Please review.

The solution should probably be found in 🐛 Compatibility issue: Route update.theme_install does not exist in Drupal 11.0.x Active .
