Was that issue there from the beginning or did it start later? If the problem started happening later, it might be necessary to try a save game where it still worked. Sometimes save games get messed up at some point for weird reasons.
Depending on what type of controller you are using it might be a good idea to close anything that might use similar buttons and therefore interfere in some weird way. Disabling all overlay features might also be a good idea (Fraps, Steam, Discord and so on...).
Mods can also cause all sorts of problems, in case you already installed a mod.
