Question Razer Cynosa Pro keyboard has stopped registering "Spacebar + "D" ?

[ElThunderCloud]

My Razer Cynosa Pro RZ03-0147 keyboard has stopped registering the Spacebar+D combination, instead only D goes through. It's fine for W/S/A+Spacebar but it's just D that breaks it for some reason. I know some keyboards don't support certain key combinations but considering it's a gaming keyboard it's weird that it would just stop working.
It's not new, obviously, it's been out of shelves for a couple years now but I just wanna make sure there isn't an easy fix before buying a new one.

It is a membrane keyboard, so no luck changing the key switch. Still, perhaps some gunk has gotten into it, disabling this key combo.

Pull off all keycaps and clean the KB innards.

Another "fix" would be rebinding the key. E.g you press Space + E but it actually registers as Space + D (by binding D to E).

Other than these two, buy a new KB.
