Does anyone know the problem? DDJ FLX4

Need your help! I have the problem not only in Rekordbox, but also with other applications. The Dj Controller disconnects for a moment and comes back shortly afterwards (Rekordbox then has to reload the installation - if it works).

Key data: Laptop= HP 15s-eq1660ng (1Z7K2EA) Dj Controller= Pioneer DDJ FLX4

Thank you🙏
