URGENT: Can't Resolve `Undefined variable $user` Error in Blade After Laravel Troubleshooting Attempts

I am completely stuck on a Laravel project right now and it’s genuinely driving me crazy. I’m just trying to implement a simple user profile view, something that should be straightforward in Laravel development, but I've been wrestling with this for hours. It’s reached the point where I feel like I desperately need some 'Laravel Quick Fix & Consultation' because I just can't see what I'm missing.

The problem is, I'm consistently getting an Undefined variable $user error in my Blade template. I am absolutely certain I'm passing the data from the controller, but the view just isn't receiving it. It feels like I've tried every single Laravel troubleshooting step imaginable for this type of error.

So far, I've:

• Verified the controller logic multiple times, double-checking the compact() or with() method.
• Checked route parameters to ensure they match and are correctly defined.
• Used dd($user) right before returning the view in the controller, and the data is there, perfectly fine!
• Cleared all Laravel caches (`php artisan cache:clear`, `view:clear`, `config:clear`, `route:clear`).
• Scoured my code for any typos in variable names or Blade directives.

Here’s the relevant part of my controller and the Blade snippet:

// UserController.php
public function show($id)
{
    $user = User::findOrFail($id);
    // dd($user); // This shows the user data correctly
    return view('users.profile', compact('user'));
}

// users/profile.blade.php
<h1>Welcome, {{ $user->name }}</h1>
<p>Email: {{ $user->email }}</p>

The error points directly to the line <h1>Welcome, {{ $user->name }}</h1>. What on earth am I missing here? Is there some obscure common pitfall for this specific `Undefined variable` error that I'm overlooking? I urgently need an expert eye on this.
