Steps to reproduce

app download from github, install is normal, email list is normal, all other functions are normal.

however, attachments in any emails cannot be opened and displayed correctly. after downloading, the attachements (e.g., pdf, doc, or other formats) are opened by the defaul app, but all are empty (with a warning, "path error") should note that K9 6.904 works well for the same emails and the same attachments in the same phone.

have tried this many times. always the same results: the three beta versions of 8.0 do not work, while 6.904 version works normally.

Expected behavior

attachments in any emails cannot be opened and displayed correctly. after downloading, the attachements (e.g., pdf, doc, or other formats) are opened by the defaul app, but all are empty (with a warning, "path error") should note that K9 6.904 works well for the same emails and the same attachments in the same phone.
