@r0umi , thank you for your report. Please make sure that you use the official release of the Magento 2 blog extension by Magefan also the problem can be in some module that extends Magefan blog.

We have checked our code base https://github.com/magefan/module-blog/search?q=BackButton&unscoped_q=BackButton and we can find BackButton only in the UI component XML, but it is actually Magefan\Community\Block\Adminhtml\Edit\BackButton and not Magefan\Blog\Block\Adminhtml\Edit\BackButton

So I recommend you to check your code and replace Magefan\Blog\Block\Adminhtml\Edit\BackButton with Magefan\Community\Block\Adminhtml\Edit\BackButton

Hello,

This issue comes from an override in our code. Thank you for the reply and sorry for the disruption.

You can close this ticket. Regards, Romain
