I am continuing to experience this behaviour in other files and projects.
i don’t see any errors anywhere.
Composer looks like it is working on suggesting the edits, I can see the status in the tabs chugging along, and then the ‘Accept All’ button becomes clickable, but there are no suggested edits.
So it is like Composer is saying:
“And here are some amazing suggestions for you - et voila! …”
But then there are no suggested changes visible.
