Encountering an issue with file uploading in Firebase: Error message indicates that AppCheck is being utilized before activation

I am facing an issue while trying to upload a file to my firebase account. Whenever I attempt this, I encounter the following error message:

Uncaught (in promise) FirebaseError: AppCheck: AppCheck is being used before activate() is called for FirebaseApp [DEFAULT]. Please make sure you call activate() before instantiating other Firebase services. (appCheck/use-before-activation).

Here are the steps I have taken so far:

  1. I disabled authentication rules for development purposes and set up the following rules:

    rules_version = '2';
    service firebase.storage {
      match /b/{bucket}/o {
        match /{allPaths=**} {
          allow read, write: if request.auth != true;
        }
      }
    }
    
  2. I installed the firebase package in my Vue Cli App using the command:

    npm install --save firebase
    
  3. I initialized firebase in my App with the following configuration:

     import firebase from 'firebase/app';
     import "firebase/analytics";
     import "firebase/storage";
     import 'animate.css';
    
     var firebaseConfig = {
       apiKey: "*API KEY*",
       authDomain: "lgu-cantilan-hrms.firebaseapp.com",
       projectId: "lgu-cantilan-hrms",
       storageBucket: "lgu-cantilan-hrms.appspot.com",
       messagingSenderId: "*SENDER ID*",
       appId: "*APP ID*",
       measurementId: "*G-8ZQZT5BCZQ*"
     };
     // Initialize Firebase
     firebase.initializeApp(firebaseConfig);
     firebase.analytics();
    
  4. Included the necessary setup in my file upload component:

    <template>
       <v-dialog v-model="dialog" max-width="800">
         <template v-slot:activator="{ on, attrs }">
           <v-btn
             elevation=""
             color="blue white--text"
             class="ml-10"
             v-bind="attrs"
             v-on="on"
             @click="dialog = true"
             ><v-icon class="mr-2">mdi-file-outline</v-icon>View Files</v-btn
           >
         </template>
         <v-card>
           <v-toolbar color="red" dark>
             <span class="headline mr-2">Files</span>
             <span class="ml-10">
               {{ employee.last_name }}, {{ employee.first_name }}'s Files</span
             >
           </v-toolbar>
           <v-card-text>
             <div class="pa-5">
               <span class="primary--text overline">Add A File</span>
               <div class="mb-5 mt-2">
                 <input type="file" class="ml-2" @change="upload_file" />
                 <v-btn small color="" @click="upload"> Submit</v-btn>
               </div>
               <v-divider> </v-divider>
               <Files />
             </div>
           </v-card-text>
         </v-card>
       </v-dialog>
     </template>
    
     <script>
     import Files from "@/components/Files/Files.vue";
     import firebase from "firebase";
     export default {
    ...
     

However, upon clicking the submit button, the console displays the following error: Uncaught (in promise):

FirebaseError: AppCheck: AppCheck is being used before activate() is called for FirebaseApp [DEFAULT]. Please make sure you call activate() before instantiating other Firebase services. (appCheck/use-before-activation).

I'm unsure of what this error signifies as I have followed the documentation instructions. Any assistance on this matter would be greatly appreciated.
