TypeError: undefined is not an object (evaluating 'window.wails._.Init')

Description

Getting this error when initializing wails in main.jsx file:

import React from 'react'
import { createRoot } from 'react-dom/client'
import App from './App.jsx'
import './index.css'

import * as Wails from '@wailsapp/runtime';

const root = createRoot(
  document.getElementById('root')
);

Wails.Init(() => {
  root.render(
    <App />)
})

but it throws an error TypeError: undefined is not an object (evaluating 'window.wails._.Init')

Wanted to init wails to use this:
    useEffect(() => {
        Wails.Events.On("checker:checked", event => {
            console.log(event)
        });
    }, []);

where i also got an error TypeError: undefined is not an object (evaluating 'window.wails.Events.OnMultiple')

Also i noticed that i have libwebkit installed sudo apt install libwebkit2gtk-4.0-dev The newest version of libwebkit2gtk-4.0-dev (2.44.2-0ubuntu0.22.04.1) is already installed. 0 packages were updated, 0 new packages were installed, 0 packages were marked for removal, and 25 packages were not updated. But in wails doctor i get | libwebkit | libwebkit2gtk-4.0-dev | Available | 2.44.2-0ubuntu0.22.04.1 | Required package(s) installation details:

libwebkit: sudo apt install libwebkit2gtk-4.0-dev
