Studio 2019: Overflow exception

Question

I recently installed Studio 2019, Windows 10 and the new Office Package. But since then the problems will not end, eg I get a strange error message when I want to open docx-files (but it works with LibreOffice). And now, when I open the file for translation in Studio 2019 I get the error message "Overflow Exception". So far I didn't encounter any problems, ie possibly footnotes are not recognised. What could be the reason for this overflow exception, and how could I solve this? 
 Thank you for your help!

I think I found the cause of my problem: it was the new Office package. I uninstalled it, and with Word 2013 everything works fine. But the footnote problem remains. They are not recognized in Studio 2019, or do I have to do something with the tags? Thank you for your help!
