tinymce conflict

Hi! I’m seeing a javascript conflict in Blocklab blocks that use the wyiswyg type when they follow a classic paragraph Gutenberg block on a page. The Blocklab blocks refuse to open until the classic paragraph block is removed or converted. Is there a fix for this?

Here’s the error being generated:

tinymce.min.js?ver=4960-20190918:2 Uncaught (in promise) TypeError: Cannot read property ‘get’ of null

It points at the tinymce file in the WordPress core directory wp-includes
