Featured image doesn’t

Greetings

I have a problem since I started using this plugin.

My featured images don’t show on social networks like Facebook or Twitter.

In the past when I entered the URL to share on Facebook for example, it took a few seconds to load. Now it looks like this: https://ibb.co/p0rpg4Q

Can you guys help me?

Thank you very much
