"Preparing file for editing" works for one Lightroom folder, but not the next.

When trying to edit a file in Topaz AI DeNoise yesterday, Lightroom had no problem "Preparing File for Editing" and then opened it up in the other app. Today, with a new folder of photos I tried it and it got hung up on "Preparing File for Editing", never opening in the other app. I tried going back to yesterday's folder of photos, and those photos still open in the other app with no problem.

Lightroom Classic version 11.1
Windows 10 - Home Edition version 10.0.19044

I am having the same issues.  On Jan 16th it worked and on the 17th and 18th I can't get it to work

Some other recently updated Topaz plugins are having such issues, e.g. Photo AI 1.17 needed a rollback to 1.16 to get it working properly. Have you updated it recently?
