Magic Keyboard fn keys not working unless plugged in??

Magic keyboard top row buttons only work when keyboard is plugged in. Option of ‘standard function keys’ in keyboard prefs also disappears when keyboard is unplugged. Tried reseting all connected factory devices and pairing them again. Reset NVRAM. Using a 2014 Imac with Mojave. Can't find any solution after many hrs of searching...Could use some help please.

SOLVED... A suggestion by 'dialabrain' was correct. I had installed 'USB Overdrive3.1' some time in the past which was only good for 10.11 and had eventually deleted the preference pane thinking I had uninstalled it. While searching through my apps I found a USB Overdrive uninstaller in my utilities. Ran that and restarted and the keyboard works. Reinstalled 3.1 and same problem. Updated USB Overdrive to 3.4 for Mojave and all good again!!

Thanks for the help from everyone. I can finally put that issue to bed.
