Lightroom Preset cannot be applied

I keep running into a serious problem with Lightroom’s AI masks: I update them while editing, finish working on an image, close my computer, and come back a couple of hours later to find that the masks have changed and the edit no longer looks right.

I can spend thirty minutes carefully editing a photo, only to return and discover a hole in the mask over a piece of clothing, leaving part of it unadjusted. It looked correct when I finished. Why is it changing afterwards?

By that point, I can’t simply press Cmd+Z to get back to the previous result. I’m left trying to reconstruct an edit I had already completed, without being able to recover exactly what I had before.

This keeps happening, and it’s costing me hours of work. It’s completely unacceptable for professional software, especially given the subscription price. Being able to close my computer and come back to the same edits should be a basic requirement.

Has anyone else experienced this? Is there a reliable way to stop these masks from changing and recover the previous result once it happens? Adobe needs to address this properly, because losing finished work like this is incredibly frustrating.

When I am editing an image and i go to update the final images after using the AI systems like masks and remove, when updating it comes up red at the top of the screen and says “Some Ai Models failed to download, please try again later”. I have tried to log out and log back in, nothing changed. I have updated my computer, Adobe, and my windows and still no good. I don’t want to resort into uninstalling my lightroom and loosing all of my weddings & events that are very important and in the process of being worked on.

Oops, ignore the second message. 

Hello! I am getting the same issue as HY3. I just downloaded/purchased lightroom classic last evening. I followed the steps you listed above and am still having the same response when I attempt to apply a preset to my images.
