Hi there,

Sorry that the shortcut for Brush (K) is freezing Lightroom.

Which exact version of Lightroom are you using (Lightroom Classic 10.1 or Lightroom Desktop) and what is your computer's operating system?

I tried replicating the issue at my end on a Windows 10 machine but it seems to be working as expected.

Would you mind deselecting the option "Use Graphics Processor" located in Lightroom's Preferences > Performance, then relaunch the app and let us know if it helps?

Thanks,

Akash
