If you want to change the credit card you use for paying subscription, you can do so by clicking on the profile icon and selecting "My account."
You can also do it by going to Settings and then "Manage subscription."
This will take you to your account settings; each of your projects have separate billing - select the one for which you'd like to edit your credit card and click "Manage billing."
You will be redirected to billing management in Stripe, where you can add a new credit card. Click on the three dots to make it the default card used for billing.
