Opening a Scrivener Document is taking forever!

Now been over 10 min Scrivener trying to open one of my documents? This is a document that has always opened seamlessly and quickly before.

What changed?

New version of Mac OS? New version of Scrivener? New hardware?

In conjunction with your other post, about text being missing, is there an issue with your internet that might keep Scrivener from downloading cloud-stored files?
