clientHold on all Route 53 domains no idea why

Hello.

I assume you've already read the documentation, but haven't you received an email at the email address you registered when you acquired the domain?
If you have received an email, please check it.
https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/troubleshooting-domain-suspended.html

In addition, when we suspend a domain, we generally send an email to the email address for the registrant contact for the domain. However, if the domain was suspended based on a court order, the court might not let us notify the registrant contact.

I put in a support case. It'll be a week today, and I've had zero response; my case is still listed as unassigned.

If you have already contacted AWS support, waiting for their response is one option.
