Hotkey already registered

Hi all

I'm recently formatted my laptop and reinstalled Snagit 2022.

I'm unable to set Print Screen as the default key for taking screenshots, getting an error "Hotkey already registered".

I'm not seeing it registered anywhere - I read a few posts on this, and already checked "Allow Snagit to override other hotkey assignments".

I've also seen others reporting OneDrive causing it, but I uninstalled that.

Any thoughts on how to check what is grabbing my Print Screen key?
