Lightroom reports "error parsing file" when exporting TAI processed image

After processing LR Classic raw image (CR3) in TAI, exporting the new LR TIF file to WIN11 desktop generates “error parsing file” mssg for about half of my images.

Using LRC (13.1), image goes through normal processing in TAI (2.3.0) and is saved back to LRC as a TIF. Currently, the save operation works but leaves an exclamation point icon on the LR image frame with pop up explanation “LR has encountered problems reading this photo”. Not surprisingly, trying to export the image produces the “error parsing file” mssg from LRC.

Note: The previous version of TAI was also generating errors immediately after saving with LR suggesting less subtlely that the TIF files were corrupt or unsupported.

I see there’s no response to this issue. Let me restate in simpler terms: Topaz AI is delivering corrupt TIF files back to Lightroom classic which then are unusable for further editing or export.

This has occurred for the last two updates of TAI.

The problem is somewhat intermittent; I recently transferred single B&W images that processed and returned uncorrupted.

Does tech support scan this forum or should I submit elsewhere?
cheers, wbd

I posted on this issue not long ago and have not received a response. It only happens using the LR Classic plug-in for Photo AI, and on images that were made B&W in LR before editing as tif files in Photo AI.
I hope someone will address this issue, as I have had to go back to DeNoise and Sharpen for B&W images.

Let’s try to reset your Lightroom plugin to try and get it working for you. You can follow the directions below to reset your Lightroom plugin:

  1. Close Lightroom fully.
  2. Run the Topaz Photo AI installer again. Get a new one from the downloads page: Topaz Labs Downloads
  3. Open Lightroom and check the File > Plug-ins Extras again.

If this does not resolve the issue go to Help > Open Log Folder, please send me all of the files within that folder.

You can securely submit your files(s) to my Dropbox using the link below.

There is a known bug with Greyscale/B&W where the output file is invalid.

Our development team is looking into this and will hopefully have a fix soon.

For now here is the workaround:

  • Convert the Greyscale/B&W image to color

  • Open and edit the color image in Topaz Photo AI and output the file.

  • Convert the color image back to Greyscale/B&W
