So sorry this happened....
I don't believe you need to create a new account if you just want to change your email address. You can go to your account and just update the email. Were you not able to do that?

There are several different ways to login to your account besides using an email address. You can use a phone number, Google, Apple or even facebook.

That said, Airbnb does need to verify the identity of any guest or host on the platform. This is a requirement, not a recommendation. Airbnb recommends you complete your public profile information that is visible to the Host, but that is optional. Sometimes Airbnb asks for for a photo ID during this process. Any pending booking will not be confirmed unless you complete the ID verification process, which may include a photo ID requirement. Hosts also have the option to require a profile photo from anyone wanting to book a stay:

Verifying Your Identity on Airbnb
https://www.airbnb.com/help/article/1237
"...As a guest, you’ll need to verify your identity when you book a stay or when you book an experience where the host has required verification. Most users only need to do this once, and we’ll guide you through any steps you’ll need to take. This typically happens during checkout—where we provide you with a specific deadline to finish. During this time, your reservation is pending, and others can’t book your dates. We’ll also send you notifications—like emails, SMS, and push reminders depending on your preferences—to help you finish before the deadline. If you don't complete the process in this timeline, your reservation won’t be confirmed..."

You can also reach out to the Host and explain the problem and see if they will hold the dates for you while you work out the ID issues. Most will gladly do that.
