Confirming that the freezing previously reported by me and confirmed by RoderickGI is still present in 27.0.38, and that it is trivial to reliably reproduce.

In the initial post in the referenced thread comox says that he has several drives. So do I. And I am having the same blocking in GUI operation.
I see that MC can wake up a drive in a background thread without blocking the GUI. But it fails when several drives are involved. I reported this in an earlier thread which was closed without solving.
My Video view contains files from 8 drives. The first 20 titles might be stored on 3 (sleeping) drives. This lets freeze MC for 10-20 seconds. Changing the sub view to 'crime' lists different titles, some stored on other drives. This takes another 10-20 seconds. This repeats 3-4 times until all drives are up and running.
After watching a movie, the other drives sleep again and blocking UI starts from the beginning. Annoying! Yes.
But I found a solution witch works for me:
I disconnect all movie drives from the network until I need it. MediaCenter works perfect without access to the media files. I do search and scroll or whatever with no delays. Only at the latest step, when the movie should start, then I go downstairs and connect that specific drive.
This gives me some extra steps up and down the stairs. But it's way less frustrating than all the 'MediaCenter is not responding' stuff.
