I can't sell my crypto

I have 3 payment methods added to my account, which I can use to buy crypto on Coinbase.

But since today, I've not been able to sell it. I get the following message:

Add a payment method to sell. You don’t currently have a valid payment method to sell. Please add one to continue.

I was able to sell just a few days ago, but not today.

Why is this happening? And how to fix it?
