Issue with Gutenberg editor

Currently we have the issue that we can’t work with the Gutenberg editor anymore. We receive the following message when editing a post: “There was an unexpected error in the editor.” Similar as it was described here: https://github.com/WordPress/gutenberg/issues/5472.

But we also get the following error message about the “Ultimate FAQ” plugin. So we think that the plugin is the reason for the issue in the Gutenberg editor. Could you explain why the following message appears and how we could solve it:

TypeError: Cannot read property ‘ultimate-faqs/ewd-ufaq-display-faq-block’ of undefined
