Answer 1

You've installed the Vuex version 3.x by running npm install --save vuex you should uninstall it npm uninstall --save vuex then install the version 4 which is compatible with vue 3 by running the following command :

npm install --save vuex@next

For people using Yarn below is the command

yarn add vuex@next

Answer 2

$ yarn remove vuex
$ yarn add vuex@next

This has fixed my issue!
