“restart the game to continue the transaction”

In the app I am unable to make purchases. It started when I went to purchase the festival pass, which I was charged for and did not receive the pass. I had been able to get a refund but ever since then I cannot make any purchases in the app at all and when I do, it restarts the game and shows a message saying to restart the game to continue transaction. I have tried that several times and tried to troubleshoot it but still cannot make any purchases in the app.
