When editing in Topaz Photo AI (3) from Lightroom, about 70% won’t export back into LR afterwards - giving me the: ‘File appears to be unsupported or damaged’ message.

Steps to reproduce issue:

1. Export file to Topaz from LR
2. Make any changes
3. Export back to LR

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.

Let me know if those steps get it working again.
