When both TinyMCE Widget and the Site Origin Page Builder plugin are installed, using WordPress 5 or greater and the block editor, (Gutenberg), when editing a non-page-builder page something happens that breaks a lot of the WP-Admin UI. Most icons in the admin bar and left-hand menu turn into boxes, alignment goes off in the left-hand menu, and any Classic blocks in the editor lose much of their TinyMCE functionality.

Steps to reproduce:
Install & Activate both Black Studio TinyMCE Widget and Site Origin Page Builder plugins.
Open a page to edit. If it's a Page Builder page turn it into a non-Page-Builder page.
Notice the icons missing from the admin bar.
Add a "Classic" block and try to add a link using TinyMCE, (nothing will happen when clicking the link button).
