Sezzle widget in product pages not working

Hello! Sezzle widget in product pages not working although I enabled it in the Payment method settings. Also, there is an error in the console:
“Refused to execute script from ‘https://tracking.sezzle.com/main-1588095099280.js’ because its MIME type (‘text/html’) is not executable, and strict MIME type checking is enabled.”

This error disappears when the “Show widget in product pages” option is disabled. I think it doesn’t work because of that.

Could you help me, please?
