Please enter a valid credit card type number

we have Magento 2.25 and recently it stopped accepting credit cards. We were originally using authorize.net and when a user enters a credit card number it comes back with an error that says “Please enter a valid credit card type number”. This error comes up right bellow the field where you enter the credit card number. Once you enter the number it happens immediately and does not allow you to checkout. We have tired different cards such as AMEX, Visa, and MC. Regardless of the card type it returns an error “Please enter a valid credit card type number”. At first we thought it was an issue with the Authorize.net module so we tried different payment solutions. We tried PayPal and it also returned the same error. Any suggestions on what may be causing this issue?

Any help would be much appreciated!!!
