How to assign an e target value in a JS file when the event is taking place from the Lightning Radio button in HTML?

I am writing a code in JS to receive name and value attributes from the Lightning-Input Radio button where an event will take place on selection. But in the JS file, it's giving me an error while assigning the event values to const variables. Please help.

HTML CODE

JS CODE
    changeHandler(event)
    {   
         const {name, value} = event.target;
         const name = event.target.name;
         const value1 = event.target.value;
         console.log('name', event.target.name);
         console.log('value', event.target.value);
        
    }

ERROR LINES Note: Just added both ways of assigning values for clarification.

         const {name, value} = event.target;
         const name = event.target.name;
         const value1 = event.target.value;
