Mask Issues - No Background/Subject Detected

[Jennifer33704756g0ma]

Sometime in the last 10 days, the subject/background detection on the masking tool has stopped working. No matter what photo I use (including the unedited copy of RAW files I have successfully used the tool on in the past), it will always fail to detect a subject or background. I have uninstalled/reinstalled Lightroom, I have checked for needed updates on my GPU, and a couple other troubleshooting tries with no change. How do I fix this??

Hey, @Jennifer33704756g0ma. Welcome to the Lightroom Community. I'll need more info to help you figure this out. 

Please share the system information from Lightroom Help > System info > Copy and paste into a text document > Upload and attach here.  

Does this happen after a series of steps, or have you installed Lightroom for the first time on this machine? This might also be similar to what is being discussed here: https://adobe.ly/3DXgoOP

Thanks!

Info attached. I have been using the cloud version of Lightroom (and this feature in Lightroom) on this computer since purchasing it in early 23 (I think that's when I bought it). The problem only started a couple weeks ago.

Thanks for sharing the System info. Your machine has two GPUs: the power-saving Intel® UHD Graphics and the high-performance Nvidia RTX 3070 Ti. 

Please try these two suggestions:
1 - Update the graphics drivers using Intel & Nvidia's auto-detect program. 

2 - Follow step 6 in the content here to configure the default GPU for Lightroom: https://adobe.ly/49YQSCI

After you update the GPU drivers, try the steps below and check how it goes. The GPU info & Logs location on Windows is %APPDATA%\Adobe\CameraRaw. A shortcut to get to this folder on Windows is:

• Press the Windows + R
• Enter %APPDATA%\Adobe\CameraRaw
  
  
• Rename the GPU & Logs folder in this directory by adding .old at the end. (GPU.old & Logs.old)
• Relaunch Lightroom.

Let me know how it goes. Thanks!
