Payment error message for newly signed up users

I have an urgent issue with payments on my template. I’ve tried using an existing user account and the payment (with an already saved credit card) always processes but we’ve had two new users get this error

Any idea how to fix? or what the cause is? I’m trying not to lose the sale/transaction so this one is fairly urgent

Stripe plugin is also updated to checkout V3 (not sure if this is why??)
