Uncaught Error: Interface

Estou com um problema ao localizar a interface no Repository de aluno, ele simplesmente não encontra. Já verifiquei os namespaces e a estrutura de pastas, porém o erro continua ocorrendo ao tentar rodar o Repository para verificar se roda sem erros. Abaixo deixo as informações:

StudentRepository.php

<?php

namespace Alura\Pdo\Domain\Repository;

use Alura\Pdo\Domain\Model\Student;

interface StudentRepository
{
    public function allStudents(): array;
    public function studentsBirthAt(\DateTimeInterface $birthDate): array;
    public function save(Student $student): bool;
    public function remove(Student $student): bool;
}

PdoStudentRepository.php

<?php
namespace Alura\Pdo\Domain\Repository;

use Alura\Pdo\Domain\Repository\StudentRepository;
use Alura\Pdo\Domain\Model\Student;
use Alura\Pdo\Infrastructure\Persistence\ConnectionCreator;
use DateTimeImmutable;
use DateTimeInterface;
use PDO;
use PDOStatement;

class PdoStudentRepository implements StudentRepository {

    private $connection;

    public function __construct()
    {
        $this->connection = ConnectionCreator::createConnection();
    }

    public function allStudents(): array {
        $sqlSelect = 'SELECT * FROM students;';
        $statement = $this->connection->prepare($sqlSelect);

        $statement->execute();

        return $this->hydrateStudents($statement);
    }

    public function studentsBirthAt(DateTimeInterface $birthDate): array {
        $sqlSelect = 'SELECT * FROM students WHERE birth_date = :birth_date';
        $statement = $this->connection->prepare($sqlSelect);
        $statement->bindParam(':birth_date', $birthDate);
        $statement->execute();

        return $this->hydrateStudents($statement);
    }

    public function hydrateStudents(PDOStatement $statement): array {
        $studentDataList = $statement->fetchAll(PDO::FETCH_ASSOC);
        $studentList = [];

        foreach($studentDataList as $student) {
            $studentList[] = new Student($student['id'], $student['name'], new DateTimeImmutable($student['birth_date']));
        }

        return $studentList;
    }

    public function insert(Student $student): bool {
        $sqlInsert = "INSERT INTO students(name, birth_date) VALUES(:name, :birth_date);";

        $statement = $this->connection->prepare($sqlInsert);

        $success = $statement->execute([
            ':name' => $student->name(),
            ':birth_date' => $student->birthDate()->format('Y-m-d')
        ]);

        if($success) {
            $student->defineId($this->connection->lastInsertId());
        }

        return $success;

    }

    public function update(Student $student): bool {
        $sqlUpdate = "UPDATE students SET name = :name, :birth_date = :birth_date WHERE id = :id;";

        $statement = $this->connection->prepare($sqlUpdate);
        $statement->bindParam(':name', $student->name());
        $statement->bindParam(':birth_date', $student->birthDate()->format('Y-m-d'));
        $statement->bindParam(':id', $student->id(), PDO::PARAM_INT);

        return $statement->execute();
    }

    public function save(Student $student): bool {
        if ($student->id() === null) {
            return $this->insert($student);
        } else {
            return $this->update($student);
        }
    }

    public function remove(Student $student): bool {
        $statement = $this->connection->prepare("DELETE FROM students WHERE id = :id");
        $statement->bindParam(':id', $student->id(), PDO::PARAM_INT);

        return $statement->execute();
    }
}
