Answer 1

The problem is, you are checking #if(Auth::user()->type == "admin") for check the logged in admin. If the admin is logged out then there is no Auth::user(). I think this is the problem you are facing. So change the condition like this
#if(Auth::check() && Auth::user()->type == "admin")
// Admin menu bar
#elseif (Auth::check())
// User menu bar
#endif
I think this will solve the issue.

Answer 2

Since the user is logged out, the Auth::user() is null.
Because of which, when you try to get its type, it is throwing
Trying to get property 'type' of non-object
You need to check whether the user is logged in, and then check its type.
#if(Auth::check() && Auth::user()->type == "admin")
Auth::check() will return true if the user is logged in

Answer 3

first check if user logged in then check that if user is admin or not:
<!-- Sidebar Menu -->
<nav class="mt-2">
<ul class="nav nav-pills nav-sidebar flex-column" data-widget="treeview"
role="menu" data-accordion="false">
<!-- Add icons to the links using the .nav-icon class

<!--Admin sidebar menu -->
#auth
#if(Auth::user()->type == "admin")
<li class="nav-item">
<a href="{{url('admin')}}" class="nav-link">
<i class="fas fa-comments"></i>
<p>Users Permission</p>

<li class="nav-item">
<a href="{{url('manage_users')}}" class="nav-link">

<p> User Register</p>
</a>
</li>
<!-- end Admin sidebar menu -->
<!-- User sidebar menu -->
#else
<li class="nav-item">
<a href="{{url('viewprofile')}}" class="nav-link">
<i class="fas fa-user"> </i>
<p>View Profile</p>
</a>
</li>
<li class="nav-item">
<a href="{{url('DashBoard')}}" class="nav-link">
<i class="fas fa-comments"></i>
<p>Chat Room</p>
</a>
</li>
#endif
#endauth
</ul>

Answer 4

use isset method
#if(isset(Auth::user()->type) && Auth::user()->type== "admin")
you can also use Auth::check()
#if(Auth::check() && Auth::user()->type== "admin")
