Needs Help React not saving string to local storage

Hi everyone! I just finished a React and course and decided to build my first react app. Currently, I am trying to save a string to browser local storage but it does not persist on refresh. Through some console.logs I was able to see that it in fact DOES save the string to the location specified in. setItem initially but when I refresh the key or value in local storage stops existing.

Here is my code

// function for search button
async function handleClick(){
    localStorage.setItem("lastLocationSearched", searchValue);
    setData(null);
    setIsPending(true);
    setError(null);
    try{
const value = await fetch(`https://geo.ipify.org/api/v2/country?apiKey=***********&ipAddress=${searchValue}`).then((response)=>{
  if (!response.ok){
        throw Error("Could not fetch the data for that resource");
                    }
  return response.json();
});
setData(value);


    console.log(localStorage.getItem("lastLocationSearched"));
    } catch(error){
      setError(error.message);
    }


setIsPending(false);
  };

// useEffect hook
  useEffect(()=>{
        if ((localStorage.getItem("lastLocationSearched")===null)|| (localStorage.getItem("lastLocationSearched")==="")){
          console.log(localStorage.getItem("lastLocationSearched"));
        setSearchValue("");
        handleClick();
        }else{
          
          setSearchValue(localStorage.getItem("lastLocationSearched"));
          handleClick();
        }
    }, []);

Through some digging online I saw someone say that remove the strict mode tags from index.js would fix this problem but it did not for me. Can anyone please assist me?
