I understand that you are getting an error "Additional verification required to request certificates for one or more domain names in this request." (.ru domain zone) when validating the domain name to issue the public certificate via ACM.
Please note this error could be the results of one of two things.
1.When the certificate contains a domain that ranks within the Alexa top 1000 websites. 2.Or as of March 10, 2022 ACM has restrictions to issue new certificates for ".ru" domains until further notice.
I see in your case you will no longer be able to issue or renew certificates as your domain falls under the following domains.
.RU .BY Бел - Belarus Рф - Russian Federation .moscow .москва - Moscow .SU - Soviet Union (http://ru.com/) .RU.COM .РУС .RU.NET
All Amazon certificates for these domains will remain functional until expiration, but will not be renewable and no new certificates from these domains will be issued.
The only workaround that would work in your scenario would be to obtain a certificate from a third party that can issue a certificate for your domain, and import the certificate into ACM 
I trust the above information is helpful to you.
Please note that I personally value your feedback, please accept this answer if you find it helpful to you.
