Input/Output Error when exporting as xml and xls

I am using LibreOffice version 6.2.4.2 on Windows 10. Yesterday I tried to export a file as xml/xls, but got an input/output error.

I tried to open the file on another computer using Microsoft Excel 2007, but it did not want to open.

How do I solve this problem?

I downloaded and installed version 6.3.0 and tried again, but I still have the same issue.

What happen saving in other format or with other name?
