Impossible to open Lightroom Classic

[Jack NC]

Hello everyone,

Since this morning, after the update of Ventura 13.0 (22A380), I can't open Lightroom classic...

Here is the error message:

Failed to initialize pixel-mask storage

Failed to create lock file inside the folder: Lightroom Catalog-v12.lrcat-data.

The process cannot access the folder because it is being used by another process.

Please help 😞

I am having the same issue opening a couple of my galleries since my update to Ventura. I first was able to load & edit the images a few days ago. I'm now getting the error when attempting to open up the gallery

I take it that your catalog is on an external hard drive.

I also take it that you are not using v12.0.1 (bug fix)

Hi. GoldingD

I am still having the issue after installing Lightroom v12.0.1. I also tried another fix from a different thread where I deleted the CURRENT file in the lrcat-data "show package content". 

I have my catalog synced from Dropbox. Not sure if my problem is there. Any thoughts?

There's potential issues where conflicted copies can be created with Dropbox. My first thought is to see if there's a file ending with .lock there. If there is delete it and try again.

Also, make sure you have granted Full Disk Access to LR in Security & Privacy> Privacy

Deleting the .LOCK file worked. Thank you!!!
