I do have mutagen enabled but I didn't initially. Changes _without errors_ appear super quick! Especially with mutagen enabled. It's just when there are errors, it takes a really long time to show the error screen.

<p>Without feedback from the system I would work from the request to the CMS.
My thoughts: did you change your .htaccess recently? Does the request get to Craft CMS? Try by adding a dump and die at a high level and see the output. Did you add any template redirects?</p>

Firstly, apologies for the comical delay in my response. This totally slipped the net. I have updated the issue based on some more findings. Turns out I _am_ getting errors but it's taking a really long time to load them, especially on a secondary multisite site. I think this could be related to the nesting issue I outlined but I really have no idea. If you have any more ideas they would be welcomed, and I promise to respond quicker this time!

@Markus Anton The DDEV setup does not work with `.htaccess` files, especially since it is nginx. As you could read above and in the posted answer, mutagen is most likely the issue. It is fast in certain cases, but it also influences slow response times, since error templates work differently than the front-end ones.
