Steps to reproduce

I tried to download an xlsx spreadsheet from the android app.

1. I opened it : no issue, usual warning that I can't edit from a mobile device with the community edition
2. Tried to download using the top right 3dots menu > download
3. Selected xlsx from the list of format available
4. Got the error message pasted below, and the app crashed

This is reproducible, I tried on a different xlsx file and got the same result.
I also tried a docx but no issue with this one.

Might be related to #16213 but there is not much detail in this other issue
