Bug fix on wordpress theme

I have a WordPress theme that since V5.8 displays this error on the widgets page:

"Notice: Function wp_enqueue_script() was called incorrectly. "wp-editor" script should not be enqueued together with the new widgets editor (wp-edit-widgets or wp-customize-widgets). Please see Debugging in WordPress for more information. (This message was added in version 5.8.0.) in /home/bankcomparison/public_html/credit/wp-includes/functions.php on line 5831"

The task is to debug the theme so the notice no longer displays.

This is the theme:

This is the zip:

If you offer to build a theme or show me examples of your work you will be immediately rejected. The task is just to fix the bug. If you can do this there will be further work.
