How to resolve this error? ::: TypeError: Cannot read properties of undefined (reading '_router')

[sakship2204]

I am migrating a vue 2 app to vue 3 using migration build. The application has following dependencies:

{
  "name": "vue22-2",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "@vue/compat": "^3.1.0",
    "core-js": "^3.8.3",
    "vue": "^3.1.0",
    "vue-router": "^3.5.1",
    "vuex": "^3.6.2"
  },
  "devDependencies": {
    "@typescript-eslint/eslint-plugin": "^5.4.0",
    "@typescript-eslint/parser": "^5.4.0",
    "@vue/cli-plugin-eslint": "~5.0.0",
    "@vue/cli-plugin-router": "~5.0.0",
    "@vue/cli-plugin-typescript": "~5.0.0",
    "@vue/cli-plugin-vuex": "~5.0.0",
    "@vue/cli-service": "~5.0.0",
    "@vue/eslint-config-typescript": "^9.1.0",
    "eslint": "^7.32.0",
    "eslint-plugin-vue": "^8.0.3",
    "sass": "^1.32.7",
    "sass-loader": "^12.0.0",
    "typescript": "~4.5.5"
  }
}

I am facing this error due to which router link:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '_router')

How can I get rid of this error?
