After upgrading to 1.597 from 1.588 on Windows when a user clicks on a job they get:

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

• If you create a new job it shows correctly until the first job runs and then it shows the 500 error.
• You can select the drop-down from the Job instead and go to Configure, etc. and it shows correctly.
• Last Success, Failure, Duration show N/A
• I cannot downgrade because trying to run the unmigrate script fails with:
