Cant edit pages and posts anymore

hi
since the last update of woocommerce i cant edit pages and posts anymore. it says “http error 500” and the page is not loading. if i deactivate woocommerce plugin everything works fine. maybe the problem was that i downgraded to 2.6.9 because of some bugs and then updated to 3.0.3 again?
the phperror.log file says:

“PHP Fatal error: Uncaught Exception: Ungültige Bestellung. in /wordpress/wp-content/plugins/woocommerce/includes/data-stores/abstract-wc-order-data-store-cpt.php:86
Stack trace:

and a few more in database.
