LR will not re-publish “Modified Photos to Re-Publish“ in Publish Services-SmugMug.?

This is a new issue, since Catalina upgraded to version 10.15.7, LR 9.4 Release Camera Raw 12.4

When I hit the Publish button to update, the progress bar activates, but the x at the end of the bar turns red, and nothing happens. This is the first time this has happened, and I am wondering if it is due to a system bug. I have tried rebooting etc to no avail. Thoughts appreciated. Thanks. Adrian
