Appearance widget editor freezing when activating plugin

Hello,

After installing this plugin my widget area in Appearance freezes and I can’t add or edit widgets.

I am still able to edit my widgets in the footer and in the header, but I can’t add new ones or edit the ones I prepared and didn’t add to the site yet.

Widgets appear on the pages front-end so visitors can see them, the problem is in Appearance only.

Is there any fix to this in the pipeline? I like your plugin and I’d like to use it but like this it isn’t possible.

For more details, I use Kadence theme on WordPress 6.3.

Thanks in advance,

Claudia
