Error after installation

Hi
I installed the plugin on my site and the pages do not load in the Elementor editor showing this error: https://prntscr.com/qi00bf
If I disable the plugin, the pages load normally.

Debugging the error reads like this:
Uncaught Error: Call to undefined function obiPlabon \ get_plugins () in /var/www/mysite.netweeb.com/htdocs/wp-content/plugins/which-addon-for-elementor/which-addon-for-elementor.php: 245
