Affected products and versions

The patch is created for Adobe Commerce version:

Issue

The error Invalid state change requested prevents a customer from placing an order.

Steps to reproduce:

1. Add a slight delay during the /estimate-shipping-methods request by including a sleep() at app/code/Magento/Quote/Model/GuestCart/GuestShippingMethodManagement.php::estimateByExtendedAddress() function, so the /estimate-shipping-methods request is completed after the /shipping-information when going from shipping step to payment step during checkout.
2. Configure the session to use [!DNL Redis] with the disable_locking: 1 setting.
3. Open [!UICONTROL Stores] > [!UICONTROL Configuration] > [!UICONTROL Customers] and enable [!UICONTROL Persistent Shopping Cart].
4. Log in as a customer and add a product to the cart.
5. Let the customer session expire. Persistent cookie and the cart still persists.
6. Now go to checkout, add the shipping address and navigate to the payment section.
7. Go back to the home page or any other page and log in with the customer account.
8. Let the session expire again.
9. Now go directly to the checkout page and navigate to the payment step.
10. Try to place the order.

Expected results:

• There is no error.
• Order is placed successfully and a Thank you page is shown.

Actual results:

The error Invalid state change requested is displayed, but the order is placed.
