Will order extension make the system unplanned outage?

Summary:

I am creating the order extension in the test environment.

Maybe my "while loop" didn't break in the correct position. The system was down when I saved the order to run this extension.

When I try to enter the test environment again, it shows the message below.

How can I fix it?
