Loghtroom Classic won't save Photo AI edit and gives "An internal error has occurred. Assertion failed"error

I consistently encounter an error message from LRC when trying to save an image edited in Photo AI. The error message is: " An internal error has occurred. assertion failed!" I’m using v 2.2.1 of photo AI and iMac with Sonoma 14.1.2. I’ve kept up with all Topaz updates and have encountered this error consisttently when using the plug-in extra for raw file editing; error does not occur with jpeg editing.
Steps to reproduce issue:

  1. Step 1 - edit lightroom raw image using plug-in extra
  2. Step 2 - hit Save to Adobe Lightroom Classic
  3. Step 3 - error message consistently will appear at end of saving process

I had a look at the log file you provided.
It seems this is the culprit:

Your license has expired.

Dear Konrad82

Thank for picking this up.
I went ahead and renewed my Photo AI license.
I then tested again retrying to save a Lightroom classic image that I processed on photo AI utilizing the Plug in Extras under File menu on LR Classic.
At the end of the Save process, /I received the same “Assertion failed” error message on Lightroom .
I attached a screenshot.


Please help! As it stands, Photo AI using the plugin extra route (so that a raw image can be edited - as opposed to drag/drop which edits a tiff or jpeg version) is not usable for me.

One other thing: I did reinstall Photo AI v 2.2.1 after I renewed my license this morning

Could you please post a new log file?

Try deleting the plist files for TPAI. Others have reported this working when there are other issues. It might work here too.
If not, de-install everything to do with TPAI. Don’t just trash it. Use AppCleaner or the like. Then install completely afresh.

I deleted TPAI using App Cleaner/Uninstall and reinstalled with v 2.2.2.
Same exact problem continues - when attempting to save image processed from Lightroom Classic using the TPAI plugin extra , continue to get error message " An internal error has occurred. Assertion failed". As I prefer editing using RAW files, this continued error makes TPAI useless for me (don’t need it for editing JPEGs).
Any further ideas?

Please follow the instructions below to perform a clean install to better troubleshoot why you had this problem with Topaz Photo AI:

Make sure that you have any plugin such as Lightroom fully closed before proceeding

Start by clearing any previous plist files that are on your computer for Topaz Photo AI by following the steps in the link below:

After you have done this, disable any antivirus, firewall, VPN, or proxy software that might be active on your computer. These tools are sometimes known to interfere with the installer’s ability to download the model files.

Please also ensure that the Topaz Photo AI installer has all the proper settings in your system by going to your Mac System Settings > Privacy & Security tab and scrolling down to the security section. You will want to make sure you have 'App Store and identified developers ’ selected. Here is a video example:
