Enscape material library missing

Ahojte, moja knižnica materiálov v Enscape 3.3 sa nesťahuje, keď tam kliknem, vyskytla sa chyba. Ako môžem vyriešiť tento problém? dakujem

Can you please share a screenshot of that behavior? Does this also occur with our latest release 3.4.2 which you can acquire here?

Thank you in advance for testing.
