Why doesn't it work to stop the event from bubbling?

I want to prevent the release selection event when I click checkbox, but I can"t do it with the following methods. Solve! Thank you!
I am the .vue page + typescript
async handleCheckClick (event) {

//
//.......
var e= window.event || event;//..
e ? (e.cancelBubble = true) : e.stopPropagation();
var o = e.target ||  e.srcElement;
o.removeEventListener("click",this.trClick)

}
trClick () {}
