Problem with importing external Single-File Components (via Vue CLI)

Question

I'm learning Vue and try to build first app with vue-cli. I have simple local components that works well. But I have a problem when I want to use external components. E.g. 'vuetable-2'. I install it locally via npm using terminal:

npm install --save vue-multiselect 

Installation is succesfull and the 'vue-multiselect' folder appears in the 'node_modules' catalogue. Then I add proper references in my Single-File Component 'ms.vue' file:

<template>
    <div>
        Hello world!
        <label class="typo__label">Select with search</label>
        <multiselect v-model="value" :options="options" :custom-label="nameWithLang" placeholder="Select one" label="name" track-by="name"> 
        </multiselect>
        <pre class="language-json"><code>{{ value  }}</code></pre>
    </div>
</template>

<script>
    import Multiselect from 'vue-multiselect'
    export default {
        components: {
            Multiselect
        },
        data () {
            return {
                value: { name: 'Vue.js', language: 'JavaScript' },
                options: [
                    { name: 'Vue.js', language: 'JavaScript' },
                    { name: 'Rails', language: 'Ruby' },
                    { name: 'Sinatra', language: 'Ruby' },
                    { name: 'Laravel', language: 'PHP' },
                    { name: 'Phoenix', language: 'Elixir' }
                ]
            }
        },
        methods: {
            nameWithLang ({ name, language }) {
                return `${name} — [${language}]`
            }
        }
    }
</script>

<style>
</style>

Everything compiles well, but when I go to the browser then the page is empty and got the following error in console:

runtime-core.esm-bundler.js?5c40:5435 Uncaught TypeError: selfHook.call is not a function

I've tried with other component and got same error.

My 'App.vue' file:

<template>
    <div id="app">
        <img alt="Vue logo" src="./assets/logo.png">
        <ms></ms>                                         
    </div>
</template>

<script>
    import ms from './components/ms.vue'
    export default {
        name: 'App',
        components: {
            ms
        }
    }
</script>

<style>
</style>

What I see is that the issue appears only in Vue3. When I recreate the whole project in Vue2 everything works well. But still no idea about the core reason of the problem...
