Select People mask crashed on macOS 12 when VRAM is < 2GB.

To resolve this issue:

• Upgrade your system to 2GB VRAM.
• You can collapse the 'Select People' widget in the masking panel when processing portrait photos. Expand the widget on-demand only when the select people option is needed, to minimize the chance of a crash. For more details, see Crash on using Select People Mask.
  

(macOS only) Slow UI in the Publish Services view when Custom Display profile is used.

We are aware of this issue and are working on a fix in future releases. 

When you try to convert a .GPR file to DNG, you get the following message:

Non-raw files were not converted to DNG.

.GPR files are effectively DNGs and hence, cannot be converted to DNG.

(Enterprise accounts only) On updating to the latest version of Lightroom Classic, end users are prompted to sign in to use their app. Enterprise end users may see that their app is running in trial mode and may be prompted to start a trial or purchase a subscription if the app was deployed using enterprise serial numbers.

This issue is expected to occur if the previous installation of Lightroom Classic CC (v7.x or earlier) was licensed and deployed by your admins using an enterprise serial number. For resolution and mitigation steps, see Lightroom Classic asks for sign-in on update.

(Mac only) If you are a Creative Cloud for Teams user in China, an error message is displayed every time you launch Lightroom Classic. The error is displayed even though you have installed the app on your computer in the language specified in the message.

To resolve this error, change your operating system's setting to set Simplified Chinese as the primary OS language and then launch Lightroom Classic.
