When I open the category page on the admin and when I try to edit category I got the below error:

Fatal error: Method Magento\Ui\TemplateEngine\Xhtml\Result::__toString() must not throw an exception, caught Error: Cannot use string offset as an array in /vendor/magento/module-ui/Component/Wrapper/UiComponent.php on line 0

Do you have any idea how we can solve it!

Your answers are appreciated

Thanks!
