It is most likely something on the guest side.
Some possible reasons::
- The guest has not setup a valid payment method
Editing-removing-or-adding-a-payment-method
- The payment method needs verification
ow-do-i-confirm-my-payment-method
- The account is new and more verification is required by Airbnb
Your listing is new, but it is bookable and in the search system:

Maybe a time of payment it was not yet fully active, so then guest should try again.
