Laravel claims a model is not found (but it definitely exists)

I am currently following the TDD birdbox videos and am experiencing an issue with Laravel claiming that the Project model cannot be found. I am on the very start of it doing my first test. I have confirmed up until the part where you need to make the Model, and everything functions as it should in the video until then.

ProjectsTest.php

namespace Tests\Feature;

use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;

class ProjectsTest extends TestCase
{
    use WithFaker, RefreshDatabase;

    /** @test */
    public function user_can_create_a_project()
    {
        //Disables Exception Handling so routes can be ignored temporarily
        $this->withoutExceptionHandling();

        //Create an array of fields to check in the table
        $attributes = [
            'title'=> $this->faker->sentence,
            'description' => $this->faker->paragraph
        ];

        //Make POST request to route
        $this->post('/projects',$attributes);

        //Assert Database has the fields in the table
        $this->assertDatabaseHas('projects',$attributes);
    }
}

web.php

use Illuminate\Support\Facades\Route;


Route::get('/', function () {
    return view('welcome');
});

Route::post('/projects', function(){
	//validate
	
	//persist
	App\Project::create(request(['title', 'description']));

	//redirect
});

Project.php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Project extends Model
{
    use HasFactory;

    
}

And I am getting the error in PHPUnit

There was 1 error:

1) Tests\Feature\ProjectsTest::user_can_create_a_project
Error: Class 'App\Project' not found

I can very clearly see that Project.php is in my app\Models folder as created by the command line. Any ideas?
