widgets section doesnt load

when we try to open widgets in admin panel it never loads no matter what we try and do … its just tries to load forever and never finishes to allow us to edit anything.
we tried all browsers but still nothing.
is this a known issue/bug?

Hello,

Please go to edit the category and make sure that you have not added any HTML block shortcode as I have on my test site: https://ibb.co/FnTt2hN

If you have the shortcode then please remove it and save it. I am sure your issue will be solved.

Otherwise, send me the WP admin login details and the category page URL where the issue exists so I will check and solve it for you.

Best Regards.
