ionic buttons and side-menu disabled

Question

Im currently working on an ionic app integrated with capacitor. I have 3 pages connected with sidemenu. when i first open the page all the buttons are working properly. But when I navigate to other page and come back to the first page using side-menu, side-menu button and all other buttons are disabled. Same thing happens with all the three pages. Here's my code for side menu in all app.html:

<ion-app>
 <ion-menu side="start" content-id="main-content" >
   <ion-header>
     <ion-toolbar translucent>
       <ion-title>Menu</ion-title>
     </ion-toolbar>
   </ion-header>
   <ion-content>
     <ion-list>
        <ion-item>
            //navigate to other page-A
        </ion-item>
        <ion-item>
            //navigate to other page-B
        </ion-item>
     </ion-list>
   </ion-content>
 </ion-menu>
</ion-app>
