Ever since updating to Monterey, pressing the Fn key switches the input source (language/character set). I normally press Fn+F11/F12 to change the volume, and now every time I change the volume I also change the keyboard input source, which is super annoying:
Going to System Preferences > Keyboard > Shortcuts, I don't see the Fn key mentioned anywhere, and in particular nothing suspicious is listed in the Input Sources shortcuts (I have a single custom shortcut active there):
How can I disable using the Fn key to switch the keyboard input source?
