Export file is corrupted and cannot be opened in any means
I download the spreadsheet from a SearchKit as an .xls file and then I can't open it with LibreOffice.
I also tried to open an export from a CiviReport and got the same error.
I also tried to import in Google Spreadsheet but with the same result.
Exporting as .ods file is also not openable. Only .csv work but it looses some formatting for phone numbers.
I'm using version 2.3 on CiviCRM 5.48.2
