I tested with commerce 2.38. Patch applied successfully and PayPal payment method label appeared as it should (e.g. 'Pay with PayPal'). Yet, if I proceed with payment, cancel it I'm returned to the order information page with payment method just 'PayPal' instead of the label (behaviour the same as without the patch).
It just a heads up, I didn't test with 3.x and clean setup.
Patch #11 worked for me.
In my case I was receiving an error when importing configuration:
ResponseText: DivisionByZeroError: Division by zero in Drupal\search_api\Task\TaskManager->processBatch() (line 373 of C:\DEV\Projects\intranet\intranet-sources\modules\contrib\search_api\src\Task\TaskManager.php).
After applying the patch I didn't receive this error anymore.
Thank you
