I am using Microsoft Edge Version 120.0.2210.91 (Official build) (64-bit) so I do not think it is a browser issue. Adobe AIR is also the latest version is 50.2.4.1. I have a license for 5 computers and have this problem on all 4 computers it is installed on. I have reinstalled both AIR and Edge which did not help. Do you have any other ideas?

I am receiving the error: Line: 1 Error: 'JSON' is undefined. It happens when I click on the Customize button after loading images. How can I fix this?
