Mouse Side Buttons not working

[What-ever]

My Razer Naga Side Buttons are not working in this game, does anyone experience the same issues? I never had this problem before in any game, also not in this game but today this problem suddenly started.

I tried replugging my mouse, restarting the game and PC and restarting razer synapse. Also I checked if there is a new driver but Im already on the most recent.

Any help?
