Ok. I finally found it.
This is what WP Bakery say:

4.1 Since WordPress 5.5 update, backend editor does not work and only display shortcodes
The issue is arising from one of the plugins or theme which is dependent upon “jquery-migrate” which is no longer enabled by default since WordPress 5.5. This plugin/theme in-turn is affecting WPBakery Page Builder and causing the issue with backend editor.
To fix this, you can install a plugin: Enable jQuery Migrate Helper (https://www.ads-software.com/plugins/enable-jquery-migrate-helper/) on your setup so that there is no such issue. Please note that this is a temporary fix until the plugin/theme which causes the issue, release an update with a fix.

I’ve installed and activated the suggested plugin. Backend editor works, but the system also displays:
jQuery Migrate Helper — Warnings encountered
This page generated the following warnings:
https://avanman.com.au/test/wp-content/plugins/framework-alma/assets/js/framework.min.js:1:5746): jQuery.fn.live() is deprecated
https://avanman.com.au/test/wp-content/plugins/framework-alma/assets/js/framework.min.js:1:5896): jQuery.fn.live() is deprecated
https://avanman.com.au/test/wp-content/plugins/framework-alma/assets/js/framework.min.js:1:6844): jQuery.fn.live() is deprecated
Please make sure you are using the latest version of all of your plugins, and your theme. If you are, you may want to ask the developers of the code mentioned in the warnings for an update.
So, obviously, the theme is out of date and requires maintenance which I’ll have to pay for since “pixelthrone” author is not available anymore. Hope he’s well, considering 2020 year…
