Unable to Make Purchases in Ubisoft’s For Honor Due to Persistent Error

I frequently make purchases in Ubisoft's For Honor without any issues—until today. I successfully completed one transaction, but when I attempted to make another, I encountered a persistent error that won’t go away. I’ve tried everything: restarting my computer, waiting hours, and even troubleshooting on my own, but the error remains, preventing me from making any further purchases.

This is incredibly frustrating, especially for a game I regularly support through in-game purchases. Ubisoft, I expect a quick resolution to this issue. Please address this problem promptly so I can continue enjoying the game without interruptions or obstacles to making purchases.
