Lightroom Classice 15.01. Denoise runs when selected for an individual image or when synchronising a batch BUT the iamges are not displayed as the denoised versions in Develop or in Library view. No matter what I try it seems that Denoise just does not work anymore. I have tried auto synch whic runs throughy all the images (yawn) and then fails to actually denoise them. Also on closoing LR down the program fails to make a bnack up of the catalogue depsite it being directed to exactly the same folder it has always used. I have reset preferences and that has not worked. Any help would be apprecaited because as it stands, this is pretty unusable...

@Phil32329285mh2q , please indicate if you have the Option in Lightroom Catalog Settings, to " Automatically write metadata to XMP " selected.

Sounds exactly like this problem, which was never solved.

In your case, does the History panel show the AI Denoise step?

Hi @Phil32329285mh2q, welcome to the community!
To start, try going to Edit > Catalog Settings > General > Backup > When Lightroom Exits, then close Lightroom. In the backup window, uncheck "Test Integrity before backing up" and "Optimize Catalog after backing up", and go ahead with the backup for now.

If that doesn’t help, we can move everything from your current (and possibly damaged) catalog into a new one. To do that:

- Hold down the ALT key while launching Lightroom Classic
- Choose the option to create a new catalog and save it to your internal drive
- In the new catalog, go to File > Import from Another Catalog

This will let you merge your old catalog into the new one stored locally.
If you’d prefer video instructions, here’s a helpful walkthrough: https://adobe.ly/49jjSZh

Let me know how it goes, and feel free to reach out with any questions!
Thanks so much,
Alek

Thanks for this.

I am following your suggestions. So far LR has spent 24 hours in importing the catalogue - this seems excessive to me. I have maybe 40k photographs in the catalogue and PC was bought last year and is decently specced.

I have not been able to see yet if this has made any difference to the denoise issue or catalogue back up failures but that fact that LR is unusable is very disappointing.
