Screenshot in conflict with root patches?!?

Hi guys, something went wrong with previous update to 15.7.3, but now had evidence of some potential conflict of patches with screenshots function in Sequoia on my 2009 MBP.

The screenshot attached to this post has been made before running post-install patched. Of course, GPU acceleration was not working nor the main keyboard or the WiFi…. but the screenshot command worked just fine.

Once the root patches installed and the system re-booted… gone: [Control] + [Shift] + [4] stopped doing anything as with 15.7.3.

Does anyone know why is that happening and how to eventually fix it?

Thanks!!! 🙏
