Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
I tested the “sitemap_index.xml” and “robots.txt”, both looks perfectly fine. Even the website meta looks fine. So technically there isn’t any fault in the website. Now sudden drop in traffic can be due to various reasons.
Few of them are:
1. Update on Google Algorithm – Google did came up with an update in  March and many people have seen spikes in their traffic. So, one reason could be this.
2. Over-Optimization – As you have used Ezoic monetization. Did you perform any optimization?
 Below 2 points are just speculations
1. Not Optimizing for SERP Layout
2. Slow Website Speed
So, I would suggest please look into GSC and latest trends to understand why there was sudden drop.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Thank you
