In System Preferences ((System Settings in Ventura), >Security & Privacy, >Full Disk Access, do you see Lightroom listed? If not, do add it and try again.

The problem is not a .lock file in the catalog folder that needs to be removed. The problem is that Lightroom Classic needs to create a lock file inside the catalog.lrcat-data folder but can't. I gave the solution earlier in this thread, so just scroll back to the previous answers.

This morning when trying to launch Lightroom Classic I get the following error message:

Failed to initalize pixel-mask storage
Failed to create lock file inside the folder: Lightroom Catalog.Ircat-data.

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

As mentioned, this just started happening today. Lightroom Classic is up to date. My OS is Windows 11 which is also up to date.

Any suggestions on what is causing this and how to fix?

Thanks

Check that the folder conating the LrC catalog doesn't already have a lock file. If it does, then delete same and retry launching the application.

No, this has nothing to do with improper closing of Lightroom and a .lock file that needs to be deleted. Quite the opposite. The error says that Lightroom needs to create a lock file, but can't. This was a known issue with Lightroom Classic 12.0.1 and was supposed to be fixed in Lightroom Classic 12.1. Apparently it was not fixed completely. The discussion about the problem in 12.0.1 mentioned the following work-around, which is worth trying now as well:

For Windows:

Go to the catalog location > Open the .lrdata folder.
Delete or move the file named 'Current.'
Relaunch Lightroom Classic - twice. (The first relaunch returns the error, the following relaunch works)

I can not open Lightroom CC due to error Error Message: Failed to initialize pixel-mask storage (Windows 11)

I have read a lot of posts. I have deleted lock files, I have restarted PC numerous times. I have shut down and started PC numerous times. I did a search for lock files and found none.

I have tired the above and still can not open.
