P: Updated to 12.1 & seeing "Failed to initialize pixel-mask storage' error after relaunch (Win)

I followed the recommendation to open the lrdata file.  Renamed CURRENT to "former CURRENT".  Tried restarting Lightroom Classic 3 times, no success.  I also deleted "former CURRENT" and restarted 3 times, no success.

Running on Windows 11 (recent install), LR Classic version 12.1.0.8.   

There is no .lock file to be found anywhere.

What else?

Thanks,  Grady

@thomasm41488594 did you open the lightroom catalog-v12.lrcat-data file? It's not in the lightroom catalog.lrcat-data file. It should be in the one with a version number in the name. This is the way it shows on my library anyways, ill post some pictures to

show

I just followed this for my Mac and it has not resolved the error.   There is no longer a file called CURRENT.  Any other suggestions.  

@johnrellis I happened to have this issue happen to me on 12.1, but was due to lightroom crashing while closing the library (this happened because my MacBook keeps disconnecting and reconnecting my external drives when I close my lid, can't disable hdd sleep due to apple removing it in settings, which would cause the next time I open lightroom to throw me an error of not finding library and having to close)

Now for the person you were replying to (main reason for comment) @Ahsan27733981kfwl :

Now to fix on Mac at least, you need to go to the folder containing the lightroom catalog file and right click on the lightroom catalog file and select show package contents and then follow the steps here:

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)

*SAME ISSUE*  This happened to me WITHOUT updating. It just started one day.
Windows 11. I've uninstalled and reinstalled the latest version a couple times. Folders are set to read and write. Permissions are in order. 
Where is Adobe?

"I still don't understand how to fix the situation on a Mac."

Adobe announced that LR 12.0.1 fixed this issue on Mac, and I can't find other reports here of that error on 12.0.1 or 12.1 (there might be some but I can't find them).  

Do the menu command Help > System Info and verify you have LR 12.1 (the latest version) installed.  If not, do Help > Updates.

Hi, I still don't understand how to fix the situation on a Mac. Please can someone help, thank you! 

This is a Windows solution, is there a Mac solution? 

A fix is in this thread.
