@jhowell: Does it happen with all files or a specific file? Can you install the portable version and try it with default settings?
From your description it sounds like a deadlock. Given that there are no changes in the calibre editor code in the beta comapred to 2.85.1 it would imply something in Qt. Unfortunately, that is particularly hard to diagnose.
The only place the editor code itself uses a lock is for completion. Does the hang happen when a completion popup would normally be triggered? For instance when editing a href attribute?
