Windows layout button not working (C13 Pro)

I’m attempting to activate the Pre rack in Cubase 13 Pro, but the “Set up Windows layout” button in my Mix Console window is blacked out. Pressing it causes the console area to highlight, but no options appear.
Any advice?
Thanks!

Hi,

Could you attach a screenshot, please?

Can you try in the Safe Start Mode > Disable Preferences mode, please?
