Payment Problem

Hello,

I am getting an error in the payment system. When I use PHP 8.1, there is no problem. When I change the PHP version to 8.2 or 8.3, I get the following error when I go to the credit card payment screen. When I contacted the payment institution, they said they received the correct payment request. The error may be due to the theme.
