Thanks for filing this, @andrew.hoeveler .
I'm not able to reproduce a problem with the Shape tools button in the toolbar. I tested in After Effects Beta v23.1x38 on Mac 11.6.8, Mac 12.6, and Windows 10.
Is there an additional step needed to cause the problem? Are you using a mouse, trackpad, or a pen? Is the toolbar docked in the usual place at the top of the workspace?
