Error on opening XLSX file exported (.NET only)


When exporting to XLSX, file generate does´t open. A message: “We Have Found a Problem with Some Content in Excel”


CR2020 for .Net runtime - CR13SP30 running on Windows Server 2016 STD (Version=13.0.4000.0)

Excel for Microsoft 365

It works well when generated by CR Developer 2020 ( but not when generated by .Net Runtime at server.
It works well for XLS (both formatted or only data); the problem only affects XLSX format.
