MacBook Volume and Keyboard Brightness Keys Not Working on Boot Camp (Windows 11)

On my MacBook 11,2, the F5, F6, F10, F11, and F12 keys do not work in Boot Camp (Windows 11). I cannot adjust the volume or keyboard brightness, though I can still adjust display brightness and control media (F1, F2, F7, F8, and F9). Reinstalling the Boot Camp drivers using Brigadier did not help.
