Linux Mint Brave Desktop Browser drag and drop file into web mail client displays empty file

Description of the issue:

Running Linux Mint and Brave. When dragging and dropping a file from a cloud drive (desktop program is installed) into a new Outlook email (website), an error occurs that states the ‘file is empty.’ However, when I copy this file to a local directory (e.g. Downloads), and drag and drop, it attaches fine. I have cleared cache, buit am at a loss. This works fin in Windows/Brave

How can this issue be reproduced?

Expected result:

File attaches

Brave Version( check About Brave):

Latest (not current at the Linux desktop)
