Unable to use the PrtScrn key on Win 11, despite disabling it for default app

Hi, title says almost all. I know this has been asked before, but I haven't found any solution for my case. 

I have properly installed the latest ScreenshotCaptor version on my new Win 11 rig. SSC used to work perfectly on my old Win 7 rig.
For the record it's always running as Administrator.
All the shortcut keys work perfectly, except the most important one: PrtScr.

I figured it was due to Win 11 automatically assigning it to its default screenshot app. So I went into Win 11 settings (Accessibility > Keyboard), and I disabled it.
Unfortunately this has changed nothing.

I have read that OneDrive could also cause issues, but OneDrive isn't enabled yet on my new rig.

Can you please help? I'm open to anything, including some registry hack that would assign the PrtScr key to SSC once and for all.

Thanks in advance!

Nevermind, a reboot seems to have fixed the issue. I never thought that Windows would require a reboot just for changing a key assignment. Live and learn!
