[SalesForce] No MODULE named markup://c:bearTile found

I'm following this trailhead step-by-step but I got an error which I don't know how to resolve.

I found this similar question but the suggested solution is already implemented on my code, please advise.

bearList.js

import { loadStyle } from 'lightning/platformResourceLoader'; --> This is where I get the error 'No MODULE named markup://c:bearTile found'
import { LightningElement, track, wire } from 'lwc';
import ursusResources from '@salesforce/resourceUrl/ursus_park';
/** BearController.searchBears(searchTerm) Apex method */
import searchBears from '@salesforce/apex/BearController.searchBears';
export default class BearList extends LightningElement {
    @track searchTerm = '';
    @wire(searchBears, {searchTerm: '$searchTerm'})
    bears;
    connectedCallback() {
        loadStyle(this, ursusResources + '/style.css');
    }
    handleSearchTermChange(event) {
        // Debouncing this method: do not update the reactive property as
        // long as this function is being called within a delay of 300 ms.
        // This is to avoid a very large number of Apex method calls.
        window.clearTimeout(this.delayTimeout);
        const searchTerm = event.target.value;
        // eslint-disable-next-line @lwc/lwc/no-async-operation 
        this.delayTimeout = setTimeout(() => {
            this.searchTerm = searchTerm;
        }, 300);
    }
    get hasResults() {
        return (this.bears.data.length > 0);
    }
}
