WPBakery editor conflict / Loopback Request issue

Hi there. Love the plugin and have been using it successfully for at least a year now.

Just lately we were having issues with not seeing the content when trying to edit certain WPBakery elements (eg textbox, single image, simple button, etc).

Did the whole deactivate everything routine. Narrowed it down to this plugin. Also for some reason, Site Health was reporting Loopback Request issues when this plugin was activated. Related? Unsure. Keeping it deactivated for now tho. Just FYI.
