Finally, The problem was solved by commenting out the function _register_controls (line 41) at file:
/wp-content/themes/colormag/inc/elementor/widgets/class-colormag-elementor-widget-base.php
Example: https://dpress.gr/wp-content/uploads/2022/03/image.png
Also there is an other way to fix it, attached the response from ThemeGrill :
“Since the issue has occurred after the latest Elementor plugin, rolling back to the previous version will fix the issue for now. However, once we fix the issue, please update the theme to the latest version which will fix the issue.
Also, you can then update the Elementor to the latest version.
For a temporary solution, please roll back the elementor plugin version. here is the link to the plugin https://www.ads-software.com/plugins/wp-rollback/
Thanks for the patience.”
