TypeError: Right-hand side of ‘instanceof’ is not callable

Hello, we just installed the latest version of the plugin (1.35.0) on WP version 6.4.1 running on php 7.4.

Problem is with the story editor, we can’t apply any settings on Document-tab (Poster image, change author). UI throws the following error:

TypeError: Right-hand side of ‘instanceof’ is not callable
