Add Coupon ends up in critical error

Hi,
Clicking on “Add coupon” ends up with a critical Error

Besuche zunächst deine Website (https://www.salty-mind.com/) und überprüfe sie auf sichtbare Probleme. Besuche als nächstes die Seite, auf der der Fehler aufgetreten ist (https://www.salty-mind.com/wp-admin/post-new.php?post_type=shop_coupon) und prüfe, ob es sichtbare Probleme gibt

Seems to be there since the new update. There was no other mayor change on the website, and i was working a few weeks ago.
