Fatal error in SELECT MODE item in Styled Box

Error phenomenon in Styled Box.
When a different mode is selected in SELECT MODE, the browser itself freezes and becomes inoperable, which is fatal.
For example, changing from Number box to Feature box.
Even if the theme is changed, the symptoms remain the same.
Even after removing all plugins, the error is still the same.
Plugins, themes, and WP itself are the latest version.

I’m sorry, but please help us.
