[Issue] Payment method title randomly changed on success page

[JMLucas96]

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.

Hello @JMLucas96,

Thank you for your report and collaboration!

We have tried to reproduce the issue in the latest development branch i.e. 2.4-develop, but it seems the issue is not reproducible for us.

Whatever we select at the time of checkout, while navigating to success page, it is showing the same method.

Let us know if we missed anything.

Thank you
