Lightroom Mask Problem

[curriec79665402]

The new masks were working fine for me when first released. Now when i got to choose any mask function, a error box pops up saysing "something went wrong". I can only use the brush tool. It will not detect any person/subject or background any longer. I operate on Windows and I am using Lightroom Classic version 12.0.1. Any suggestions on what the cause is and how to fix it?

Try resetting your Lightroom preferences:

Quit Lightroom Classic.
macOS: Press and hold the Shift + Option keys.
Windows: Press and hold the Shift + Alt keys.
While holding down the keys, launch Lightroom Classic.
When asked, select "Yes".

Following all instructions above for Windows, the promt that "shift+alt" pulls up lightrrom properties not a preference reset. Any other way to do this?

Method 2: Manually delete the preferences file

• Navigate to the following location:

  macOS: /Users/[user name]/Library/Preferences/

  Windows: Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\

  Note:

  macOS: The user Library file is hidden by default. For temporary access to the user Library file, press Option and choose Go > Library in the Finder.

  Windows: The AppData folder is hidden by default. To view it, choose Start > Control Panel > Appearance and Personalization > Folder Options. In the Advanced area of the View tab, make sure that Show Hidden Files and Folders is selected. Then click OK.

• Drag the following files to the Recycle Bin on Windows or to the Trash on macOS:

  macOS: com.adobe.LightroomClassicCC7.plist

  Windows: Lightroom Classic CC 7 Preferences.agprefs

• Restart your computer and launch Lightroom Classic.

If resetting preferences doesn't help, that error message in response to using an AI mask is typically caused by older, buggy graphics drivers. Try updating your graphics driver by going directly to the manufacturer's web site:
