Nextjs _app.js work multi time only onload. (not reactStrictMode problem)

Even I tried a lot of thing I couldnt handle that problem... On page load

Problem is : _app.js works twice just onload for all pages..

reactStrictMode is false in next.config.js;

console.log(loading) response 2 times...

I dont understand if it is normal to load twice in nextjs

and here is my Code;

   import files;
    
    let Loginstatus = false;
          
    const allEnhancers = compose(
      composeWithDevTools(
          applyMiddleware(thunk,logger),
      )
    );
    
    var store = createStore(Mystore,allEnhancers);
    
    store.subscribe(() =>{
      console.log('Store updated : ',store.getState())
    })
    
    checkLog();
    
    const getData = (val) => {console.log("deneme123")}
    
    function MyApp({ Component, pageProps }) {
      const [winWidth, setwinWidth] = useState();
       
      useEffect(() => {
          if (typeof window !== 'undefined' && winWidth==null) {
            setwinWidth(window.innerWidth);
            window.addEventListener('resize', function(event) {
              setwinWidth(window.innerWidth);
            })
        }
      }, []);
    
    
    
      if(Loginstatus == null || !store || !winWidth ){
        return( 
            <>         
            <MyLoading/>
            </>
        )
      }
    
      console.log(loading)
    
      return( 
        <Provider store={store}>
          <Header logstatus={Loginstatus} winWidth={winWidth}/>
          <Component {...pageProps} logstatus={Loginstatus} winWidth={winWidth}/>
          {winWidth >700 ? <Footer logstatus={Loginstatus}/>: null }
        </Provider>
      )
     
    }
    
    export default MyApp
