Keymapping off - only in FFXIV

[DamnDam]

Hello,

this is going to sound absolutely insane but since approx. 1 week ago, when playing ffxiv, some of my keyboard input is read wrong (win11, steam version, alienware keyboard with up to date drivers).

I have a set-up that uses the function keys for my hotbars, and since a week ago, the F6 key is read as the C key in game - it constantly opens the character tab instead of executing the hotbar action. I tried to redo my keybind in-game, but when I press F6 to (re)assign it to Hotbar 2 - Slot 6, it comes out as C, with the warning that C is already assigned to Character. C is still read as C. If I remove the F6 keybind, its impossible to reassign.

I first noticed while crafting and thought maybe it was a weird new crafting mode thing, so I shrugged it off even though it was annoying, but I was just practicing with the practice dummy at my fc house and realised this was a more general issue.
1 week is an approximation because I don't always have an action on F6 on the class I'm currently leveling so it may just have gone unnoticed.

No other key has this issue (that I'm aware of), and this doesn't happen outside of ffxiv. I haven't done or changed anything to my pc (no updates or anything - that I'm aware of), and my mouse&keyboard set-up has been steady for years. Rebooting the game or my pc doesn't change anything.

Does anyone know whats up with this? I appreciate any help at this point because I've tried everything I could think of and my friends are stumped too.
