Windows 10: Only able to use function keys F3 to F6

I've recently encountered an unusual issue with my Keychron K8 keyboard on a Windows 11 system. For some reason, I am only able to use the F3 to F6 function keys directly. To use the rest of the function keys F1, F2, F7-F12, I need to press them in combination with another key for example, "S + F2". This problem persists even when booting the computer in Safe Mode, suggesting that it's not caused by third-party software interference. However, when I tested the keyboard on another computer, all the function keys functioned correctly.

Volume function keys (F1 - F3) not working properly

My F1 to F3 function keys (which also double as mute, vol down, and vol up) don't work as they should. Whenever I press these keys it refreshes my screen and bugs out for a few seconds - can't seem to find a similar problem anywhere.

• Running: Windows 11 (Build 22533.1001)
  
• Device: Dell XPS 13 9370.
  

I know I am on a dev build of windows and this only happened after a recent update but has anyone got any ideas how I might be able to fix it. (All of my FN keys work normally apart from these 3). I already tried reinstalling keyboard drivers etc.

This might help as well:

• Pressing Fn lock + F1 opens support page in browsers
  
• Pressing Fn lock + F3 opens find in browsers (The same as Ctrl + F would)
  

I know someone is going to put this as a solution: just turn off/on function lock, but that doesn't seem to be the problem.
