Laravel testing database table is being accessed by other users

I'm currently building a multi-tenant application using stancl/tenancy (every tenant uses their own database) in my Laravel application.

Whenever I'm writing tests, tests fail a lot due to the error

Illuminate\Database\QueryException: SQLSTATE[55006]: Object in use: 7 FEHLER:  auf Datenbank »tenant_019949ce« wird von anderen Benutzern zugegriffen
DETAIL:  1 andere Sitzung verwendet die Datenbank. (Connection: tenant_host_connection, SQL: DROP DATABASE "tenant_019949ce")

which means the table is used by another user. Tables are created when a tenant is created and should be deleted if a tenant gets deleted but it always fails in tearDown method.

My tests extend TenancyTestCase class:

use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

class TenancyTestCase extends BaseTestCase {

    use RefreshDatabase;

    private Tenant $tenant;

    protected function setUp(): void {
        parent::setUp();

        Config::set('tenancy.seeder_parameters.--class', TestDatabaseSeeder::class);

        $this->setupDefaultTenant();
        $this->forceRootUrl();

        $this->withoutVite();
    }

    private function setupDefaultTenant(): void {

        $this->tenant = Tenant::factory()->create();
        $this->tenant->domains()->save(Domain::factory([
            'domain' => 'tenant',
        ])->make());

        tenancy()->initialize($this->tenant);
    }

    private function forceRootUrl(): void {
        $parsed = parse_url(config('app.url'));
        $host = $parsed['host'] ?? 'localhost.test';
        $port = isset($parsed['port']) ? ':' . $parsed['port'] : '';

        URL::forceRootUrl('https://tenant.' . $host . $port);
    }

    public function tearDown(): void {
        tenancy()->end();
        $this->tenant->delete();

        parent::tearDown();
    }
}

I couldn't figure out why yet, any ideas on how to fix this?

My goal is to create a single database for each test and delete them if test is completed.

Thank you.

EDIT: If I comment Jobs\DeleteDatabase::class out, it works fine but the database will still persist which is not what I want. But tests are successful. So how to delete database correctly?

Events\TenantDeleted::class => [
    JobPipeline::make([
        Jobs\DeleteDatabase::class,
    ])->send(function(Events\TenantDeleted $event) {
        return $event->tenant;
    })->shouldBeQueued(true),
],

I also found out that every tenants database that is created DURING the test itself (not in setUp) get's handled and deleted correctly. But not the original one.
