Strange mouse behavior

[Selestial]

I use the mouse in the picture because it helps my wrist not hurt. I use it for everything from editing, browsing the web, and especially gaming. It's been probably the greatest mouse I've ever used personally in games, but recently, I've noticed a small problem with it. I'm not sure if the mouse is doing it or if it's related to windows 11, but when I'm in game, (currently borderlands 2, happened in 1) I'll go to use scope because I'm a sniper most of the time and I'll go to shoot. I'll get stuck in scope like I'm still holding on to the button when my finger comes off and I'll still be shooting. I've taken my hand completely off the mouse and it'll stay scooped and firing until I apply the buttons again. It doesn't happen all the time, but at random and seemingly only when the worst possible time is, but that's irrelevant lol. This never happens if I don't scope, but being a sniper, I kinda need to sometimes. Had anyone else experienced something like this? I can confirm there's nothing mechanically wrong with the mouse and I'm not using the Kensington software. It's plugged into USB raw. It doesn't matter if I'm using my laptop or desktop, both which have windows 11.

Also, please ignore the finger dirt. It collects it. It's the only downside to the mouse that I have to clean in all the time because of the underside picks up from the table and surrounding area. The inside is spotless so I know it's not that.
