After upgrading to Big Sur and Xcode 12.2, the app crashes every time I select the behaviors preference pane.

I can see the following error in the crash report:

Code Block ProductBuildVersion: 12B45b
Crashing on exception: The window has been marked as needing another Layout Window pass, but it has already had more Layout Window passes than there are views in the window. 
<NSPanel: 0x7f9a85f69130> 0x9ed (2541) {{545, 363}, {830, 552}} Behaviors en

Anyone else experiencing this?
