Acer Nitro Mouse. Need Help with side buttons - Nitro 5 AN515-55

I've just recently bought my Acer Nitro 5 laptop with the headset and mouse and for the first few days the mouse had no problems. After 3 or so days the side buttons dont work in games anymore when it worked before. The problems are in mb4 and mb5 as they seem not to register in the games. Opera GX detects them and when I click on them while in Opera they do the Back and Forward buttons. While playing a game however for example Apex or League of Legends they dont get detected or something, before it worked completely and i was able to bind them to buttons but now i cant even do that. If you have any solutions please help.
