laravel 5.4 pagination issue invalid argument supplied for foreach() - laravel-5

Question

I have around 50 objects in an array.
$user = User::with('abc','def','ghi','jkl','mno','pqr')
->where([['id', '<>', Auth::user()->id],['role', '<>', 2]])->simplePaginate(15);
$users = json_decode($user,true);
Have I placed ->simplePaginate(15) this correctly? Can I do json_decode after that? like I am doing? I dont get any error in controller.
In Views
#section('content')
<div class="container-fluid">
<div></br></br></div>
#include('errors.list')
<div class="row">
#foreach($users as $user)
<a href="#" onclick=document.getElementById('{{$user->id}}').style.display='block'>
<div class="col-md-3" style="margin-bottom:50px;">
#if($user["search_status"] == 'matched')
<div class="w3-card-12-disabled" style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
#else
<div class="w3-card-12" style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
#endif
<img align="center" src="{{$user->photo}}" style=" border-radius:50%; ; border-style: solid; border-color: #333; border-width: 5px; margin-left:15%;" width="150px !important" height="150px !important" />
<h3 style="color:#000;

#endforeach
<div class="row">
#foreach($users as $user)
<div id="{{$user->id}}" class="w3-modal">
<div class="w3-modal-content w3-animate-top w3-card-8">
<div id="div1" style="padding:40px 30px 30px 30px;">

{!! Form::hidden('_method', 'POST') !!}
{!! Form::hidden('friend', $user->id, null, ['class'=>'form-control']) !!}
{!! Form::submit('Report', ['class'=>'btn', 'style' => 'padding: 10px 10px 10px 10px; color:#000; border-color:#000;']) !!}
{!! Form::close() !!}
</div>
</div>
<div id="div2" style="padding:40px 0px 40px 0px;">
<span onclick=document.getElementById('{{$user->id}}').style.display='none'
class="w3-closebtn">×</span>
<h1>{{ $user->firstname}} {{ $user->lastname}}</h1>
</br>
</br>
<h5 style="padding-top:30px;"><b>About Me:</b> {{ $user->bio}} </h5>
<h5 style="padding-top:10px;"><b>Campus:</b> {{$user->campus->campus_name}}</h5>
<h5 style="padding-top:10px;"><b>School:</b> {{ $user->schools->schools_name}} </h5>
<h5 style="padding-top:10px;"><b>Year:</b> {{ $user->years->years_name}} </h5>
<h5 style="padding-top:10px;"><b>Native Speaker of:</b> {{$user->natives->language}} </h5>
<h5 style="padding-top:10px;"><b>Second Native Speaker of:</b> {{ $user->snatives->language }} </h5>
<h5 style="padding-top:10px;"><b>Seeking Speaker of:</b>
#foreach($seeks as $seek)
#if($seek->user_id === $user->id)
{{ $seek->language}},
#endif
#endforeach </h5>
</div>
</div>
</div>
#endforeach
</div>
{!! $users->links() !!}
</div>
</div>
#endsection
Even if I dont put this code {{ $users->links() }} in view I still get same error. I guess issue is with the pagination code on controller.
Edited
I have this small issue still:
Before
<h5 style="padding-top:10px;"><b>Campus:</b> {{$user['campus']['campus_name']}}</h5>
<h5 style="padding-top:10px;"><b>School:</b> {{ $user['schools']['schools_name']}} </h5>
<h5 style="padding-top:10px;"><b>Year:</b> {{ $user['years']['years_name']}} </h5>
<h5 style="padding-top:10px;"><b>Native Speaker of:</b> {{$user['natives']['language']}} </h5>
<h5 style="padding-top:10px;"><b>Second Native Speaker of:</b> {{$user['snatives']['language']}} </h5>
<h5 style="padding-top:10px;"><b>Seeking Speaker of:</b>
#foreach($seeks as $seek)
#if($seek->user_id === $user['id'])
{{ $seek->language}},
#endif
#endforeach </h5>
After
<h5 style="padding-top:10px;"><b>Campus:</b> {{$user->campus->campus_name}}</h5>
<h5 style="padding-top:10px;"><b>School:</b> {{ $user->schools->schools_name}} </h5>
<h5 style="padding-top:10px;"><b>Year:</b> {{ $user->years->years_name}} </h5>
<h5 style="padding-top:10px;"><b>Native Speaker of:</b> {{$user->natives->language}} </h5>
<h5 style="padding-top:10px;"><b>Second Native Speaker of:</b> {{$user->snatives->language}} </h5>
<h5 style="padding-top:10px;"><b>Seeking Speaker of:</b>
#foreach($seeks as $seek)
#if($seek->user_id === $user->id)
{{ $seek->language}},
#endif
#endforeach </h5>
This gives After code gives me error trying to get property of non-object which is why I was using json_decode() and Before code. How do I fix these?

You don't need to json encode anything and access the object property directly.
Controller
$users = User::with('abc','def','ghi','jkl','mno','pqr')
->where([
['id', '<>', auth()->id()],
['role', '<>', 2]
])->simplePaginate(15);
return view('someview', compact('users'));
View
<div class="row">
#foreach($users as $user)
<a href="#" onclick="document.getElementById('{{ $user->id }}').style.display='block'">
<div class="col-md-3" style="margin-bottom:50px;">
#if($user->search_status == 'matched')
<div class="w3-card-12-disabled"
style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
#else
<div class="w3-card-12"
style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
#endif
<img align="center" src="{{ $user->photo }}"
style=" border-radius:50%; ; border-style: solid; border-color: #333; border-width: 5px; margin-left:15%;"
width="150px !important" height="150px !important"/>
<h3 style="color:#000;
padding-top: 20px;" align="center">{{ $user->firstname }}<br/>{{ $user->lastname}}</h3>
<br/>
</div>
</div>
</div>
</a>
#endforeach
</div>
{!! $users->links() !!}
