I filed a bug yesterday and today Adobe support got back to me saying they were able to reproduce the issue on there end and have already escalated it to our engineering team for further investigation. It’s being tracked under Bug ID AN-373512.

I also am having this same issue.  Unfortunately, I'm not able to save at all.  Any solutions here?

@bindukumari90or @pradnya_balvir  - Were you able to find a solution to this?  I am having the same/similar issue and am looking for a fix.  Thank you.
