Website crash whit enabled “Codeless Framework” plugin.

Problem:

As soon as the "Codeless Framework" plugin is activated, the website crashes. There is then nothing else to do, but via phpMyAdmin in the database, under WP_options and Option_name "Active Plugins" empty it (thereby disabling all plugins). Then the website works again and the plugins can be activated again.

[I just ran a few updates, and tried again, but the problem remains].

Current situation:

Website version: WordPress 6.4.2.-NL
CodelessFramework version: 1.0.6

Theme: Specular - with a custom Specular Child theme Tensor
Builders/editors used:
WP - Bakery Page Builder
With a special plugin Specular WPBakery Addons & Backward Compatibility
Redux Framework
Elementor
Visual Composer

Codeless Framework Plugin (thus causing the problems) works closely with the Specular Theme.
Furthermore, there are several other plugins running, which do not seem to be causing problems.

If I turn off all the plugins and then turn on codeless, it still immediately goes wrong. 


I turned on wp_debug,and have an detailed log available.
