Error when editing Product

Hi, i’m getting a (probably) compatibility error when i activate your Plugin an try to edit a Product. The Editor page doesn’t load fully, the buttons from your Plugin are there but non-functional and all editor elements below the variation view are not loaded

I got the following stacktrace:

 (probably)Ein Fehler vom Typ E_ERROR wurde in der Zeile 118 der Datei /[root directory]/wp-content/plugins/trusted-shops-easy-integration-for-woocommerce/src/Admin/Helper.php verursacht. Fehlermeldung: Uncaught Error: Call to a member function get_meta() on bool in /[root directory]/wp-content/plugins/trusted-shops-easy-integration-for-woocommerce/src/Admin/Helper.php:118

Is there an obvious fix for this?
