Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
It sounds to me you got hit by an algorithm update and I am sorry that Rank Math would not cause a drop in rankings.

If a URL is on Google, there is technically no reason for it to not be included in Bing unless Bing has some reason to not index a page like DMCA, copyright content, nulled content, copied content, etc.
I would request you to contact Bing to know the exact reason as from checking the page source, there are no apparent issues.
You could also try various site audit tools to check if there is any issue with your websites.
I hope this helps. Looking forward to helping you.
