LrC tool bar locks up

Hi ​@digital paradise,

Thanks for reporting this and for your patience. Since your report was based on Lightroom Classic 15.4.1, could you first update to the latest Lightroom Classic 15.5 & macOS 15.7.9 and check whether the toolbar still becomes unresponsive after Lightroom has been running for some time?
 

If the issue persists, could you please share:

• System Info: Go to Help > System Info, click Copy, and paste the contents here.

• Approximately how long Lightroom Classic needs to remain open before the issue occurs.

• Whether Lightroom itself continues responding when the toolbar locks up, or whether the entire application eventually becomes unresponsive.

• A short screen recording showing the behavior, if possible.

Since this develops over time rather than immediately after launch, those details will help us narrow down what may be triggering it.

Best,

Anshul Saini
