Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Upon checking your website, I noticed you don’t have any og:image present on your page source.
Please make sure you have added a featured image to your homepage or you please check if the default thumbnail is properly set. You may check it by heading to your WordPress Dashboard > Rank Math > Titles & Meta > Global Meta:
https://i.rankmath.com/kN9XUo
Also, make sure you have cleared your website’s cache after doing so.
You may also refer to this handy guide: https://rankmath.com/kb/open-graph-image-not-displaying
If that doesn’t work, please check if there are other active plugins or your current theme that is conflicting with Rank Math. To determine that, you may follow this handy troubleshooting guide: https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
Let us know how it goes. We are looking forward to helping you.
