I can't download a ZIP file from the Sitefinity CMS Export / Import menu

Question

I want to download a ZIP file from Sitefinity CMS Export / Import menu, but after I clicked "Export to ZIP file" button I've got this error: Data have not been successfully exported. I've tried to export each item individually, but the result was still the same.

Steps to reproduce: Go to Sitefinity CMS (Admin site) -> Administration -> Export / Import -> Download ZIP file -> select just 1 item -> click "Export to Zip file" button -> the error appears on the Browser: Data have not been successfully exported.

Detail error message, On the CMS: Data have not been successfully exported

On the Chrome DevTools: Response Code 500. ErrorCode: InvalidOperationException. Message: Scheduling is not enabled Response Code 500. ErrorCode: InvalidOperationException. Message: Scheduling is not enabled
