Nuxt fonts working locally but not on built version

Question

The problem I am facing is when I run the project using npm run dev, the fonts are loaded exactly how I want

but when I make a build and run the command npm run start, the fonts are different

This is how my nuxt.config file looks like

var dynamicPages = require('./dynamicPages.json')

export default {
  // Target: https://go.nuxtjs.dev/config-target
  target: 'server',
  buildDir: '_nuxt/dist/',
  // build: {
  //   publicPath: '_nuxt/dist/'
  // },

  generate: { routes: dynamicPages },

  // Global page headers: https://go.nuxtjs.dev/config-head
  head: {
    title: 'level-1',
    htmlAttrs: {
      lang: 'en'
    },
    meta: [
      { charset: 'utf-8' },
      { name: 'viewport', content: 'width=device-width, initial-scale=1' },
      { hid: 'description', name: 'description', content: '' },
      { name: 'format-detection', content: 'telephone=no' }
    ],
    link: [
      { rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' }
    ],
  },

  // Global CSS: https://go.nuxtjs.dev/config-css
  css: [
    '~/assets/styles/style.scss',
    '~/assets/fonts.css'
  ],

  // Plugins to run before rendering page: https://go.nuxtjs.dev/config-plugins
  plugins: [
    { src: '~/plugins/analytics.js', mode: 'client' }
  ],

  // Auto import components: https://go.nuxtjs.dev/config-components
  components: true,

  // Modules for dev and build (recommended): https://go.nuxtjs.dev/config-modules
  buildModules: [
    '@nuxtjs/google-analytics'
  ],

  apollo: {
    clientConfigs: {
      default: {
        httpEndpoint: "https://rickandmortyapi.com/graphql"
      }
    }
  },

  // Modules: https://go.nuxtjs.dev/config-modules
  modules: [
    // https://go.nuxtjs.dev/bootstrap
    'bootstrap-vue/nuxt',
    'nuxt-helmet',
    '@nuxtjs/apollo',
    'nuxt-helmet',
    'nuxt-webfontloader',
    '@nuxtjs/gtm',
    'nuxt-fontawesome',
  ],

  router: {
    // trailingSlash: false,
    middleware: 'trailingSlashRedirect',
  },

  fontawesome: {
    imports: [
        {
          set: '@fortawesome/free-solid-svg-icons',
          icons: ['fas']
        },
        {
          set:'@fortawesome/free-brands-svg-icons',
          icons: ['fab']
        }
    ],
  },


  // Build Configuration: https://go.nuxtjs.dev/config-build
  build: {

    // extend (config, ctx) {
    //   // Run ESLint on save
    //   if (ctx.isDev && ctx.isClient) {
    //     config.module.rules.push({
    //       enforce: 'pre',
    //       test: /\.(js|vue)$/,
    //       loader: 'eslint-loader',
    //       exclude: /(node_modules)/
    //     })
    //   }
    // }
  },
}

is there an issue with how my nuxt file looks like? any suggestions?
