When adding an Excel file .xlsx to a project in Studio 2021 SR2, the xliff is empty (0 words). When opening it I only see the path on my computer, but no file

In the column Words: 0, in Files Satus: Unspecified; size: 131KB; Usage: Translatable; File type identifier: SpreadsheetML v.1

I use Microsoft Office 2016, and the file type Microsoft Excel 2007-2019 is checked in the Project settings.

Thanks for your help!
