P: Lightroom V14.4 - Error when attempting to use new Denoise - Attempt to index a nil value

@anne_9459 

- (backup your photos and) make note of the number of photos in your catalog

- create a New Catalog (in the same folder for other references)

- make sure to pause Syncing with the web before you continue

- Import from Another Catalog and select your current catalog file; this can take some time

- check the number of photos in your catalog (reimport the missing folders if necessary)

If you've created XMP files before, LrC will show an exclamation symbol for conflicting edits: click to choose for external or for your LrC edits. To keep your LrC edit history, choose the latter. (Are there official Adobe recommendations for this?)

You should be able to Denoise, Remove Distractions etc. now.

- make sure to Optimize and set up Backup of your new catalog.

I created a new catalog and have had no problems at all. I didn't want to create a new catalog, but in it everything works fine. The Denoise feature works well and the file names don't end up with that obnoxious NR addition. So, create a new catalog and motor right along. 

Hi, new to this forum, but what I am reading here is exactly what I am getting.

LR upgraded to the latest - I didn't request it so must have automatically done it (annoying!)

And now I cannot denoise any existing photo or any new one I import, everything else is perfectly fine.

The error is 
?:0: Attempt to index a nil value 

Just as I am needing to use LR more and more for photography, its been so good up until this. 

I am still having the error. Has anyone figured out a way around this?

The problem is with all images

@raeuberli 

Ok so for that image the workaround with History/Protokoll is not doable.

You can't click the Denoise checkbox ONLY for that image or all images

.

@raeuberli 
History can be found in Develop module on the elft side panel (see screenshot)
 

If you don't see it then you hid it.
To make it visible then right click on the presets panel (which I see you have enabled) and tick "History"

Jetzt habe ich es gefunden:

In German it is called Protokoll (History) 🙂

The history is empty after I try to start the denoising process. No entry is made there.

@C.CellaSorry, but I am somehow too stupid for this 🤓
Where can I find the "History" window?

@raeuberli 

Click the X in the History panel to clear all (see screenshot)



Or right click on the Step before doing Enhance and do "Clear History Above This Step" (see screenshot)


Or hold Alt/option modifier and click the step to do "Clear History Above This Step" fast.
