Mouse can't shoot while aiming(Everest Mouse)

I hope this issue will be solved because I'm very frustrated.

Bought new mouse and tried it out on games but I was confused why I could not shoot while aiming down on Apex.

The problem is only occurring while playing apex and it's while I'm pressing the right click on the mouse to aim and while I'm holding it I cant shoot with the left click.

I tried other mouse but its working fine.

I also changed the mouse in the shop and when I returned home the problem disappeared for 5 minutes and I was all happy but occurred again...
