Another point could be that Lifghtroom doesn't have full access rights to the folder with the catalog file. Please check if LR does have full right to the appropriate folder.
My System: Intel i7-8700K - 64GB RAM - NVidia Geforce GTX 1050 Ti - Windows 10 Pro 22H2 -- LR-Classic 12.1 - Photoshop 24.1. - Nik Collection 5 - Topaz Sharpener AI
Hi, I am trying to open a catalog in Lightroom 12.1 on windows 11 22h2. The catalog has been moved and than moved back to original position. Now a get an error : lightroom kan pixelmaskeropslag niet initialiseren.
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.
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:
First find the Lightroom Catalog-2-2v12.lrcat-data
Then double click it.
Then rename CURRENT
Then open Lightroom, you will get error message again, then opne Lightroom again and lightroom should open. This is what I did and it worked. I hope it works for you.
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.
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.
