Yes i'm filing this because my module https://www.drupal.org/project/admin_theme_by_content_type → has the same problem! In ✨ Use admin theme for add and edit forms of some content types, but not all Active psf_ recommended implementing Theme Negotiator; is that what we need to do to avoid this problem? Or is there something else we can do in or around the Symfony\Component\HttpKernel\KernelEvents::REQUEST callback that can avoid this?

well i cannot find a way to check that there is a route before doing the match request (there probably is though?) but wrapping the attempt in an exception handler works fine. Maybe it would be better to target the specific exception if going this route (no pun intended), but this fixes the fatal error.
