Preconditions and environment

• Magento version 2.4.8-p3
• Use of $order = $this->checkoutSession->getLastRealOrder(); and then $order->getPayment() shows different payment method every time, but un backoffice payment method still correct.

Steps to reproduce

1. Make sure to have more than one payment methods to finish purchase.
2. Debug prepareBlockData() function on vendor/magento/module-checkout/Block/Onepage/Success.php
3. See how $order->getPayment()->getMethod() from $order = $this->checkoutSession->getLastRealOrder() showing another method_code each time.

Expected result

Payment method is the selected on last checkout step.

Actual result

Payment method is randomly modified

Additional information

It seems that error comes from the last checkout step, when placing order I get the following error on savePaymentInformationAndPlaceOrder method from vendor/magento/module-checkout/Model/PaymentInformationManagement.php:

Since web-token/jwt-library 3.3.0: The parameter "$contentEncryptionAlgorithmManager" is deprecated and will be removed in 4.0.0. Please set all algorithms in the first argument and set "null" instead.
