Error message: AI Edits Storage Issue

Hello, 

I have been experiencing a big bug  in my Lightroom catalog. I have this message every time I open my catalog : “Lightroom has encountered an issue updating AI edits. Futur AI edits may not be saved and could be lost.” 

I followed the recommended steps when I clicked the “learn more” button but nothing has changed. 

I have many issues linked to this error such as no successful backups made since a week, every edits made with AI such as removal, denoise, and masking have disappeared. When the AI update button is lit up on a photo to update a mask or denoise for example, it does not work. As soon as the update is over, the button is yellow again. On some masks applied previously, I have the exclamation point in the warning triangle, I cannot update them as well. Furthermore, everything linked to the AI generative removal is lost too and cannot be updated. Also, when I close Lightroom and I want to do a backup, an error message pop up saying that “Lightroom Classic has encountered a problem and needs to close”. 

I checked I have not use my AI credits. It might be due to the TAHOE 26.2 update on Mac and the new version of Lightroom. 

In the mean time I have created a new catalog for the work I need to do quickly but this issue really impacts my workflow and efficiency. If anyone has an idea or has encountered the same issue, please le me know. I am out of option right now. I am waiting for an update from Adobe or to be contacted by a technician. 

Thank you,
