Hello,
Thank you for your query and we are so sorry about the trouble this must have caused.
Can you please confirm if you are referring to the featured image shown visibly on the page or the featured images in your meta tags?
As initial troubleshooting, you may refer to this guide to see if activating only the Rank Math plugin and the default theme will help you locate the cause of the issue: https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
If that doesn’t help, can you please share the affected URL with us so we can check it on our end and advice further?
Looking forward to helping you.
