Every time I try and upload a file to Teams (both app and browser version) it fails, saying "File does not exist" but it's right there in the Desktop.
Another is Vegas, it doesn't let me drag&drop and if I import it'll say "File could not be opened. Make sure the file exists and that you have access to the file/folder."
However, I found a pattern. Both files were downloaded, both from different sources recently. I can upload/import any file that was in my PC for a long time.

I already checked permissions for the files, folders, desktop and temp folder, they're all the same for every file, I've tried uploading from other disks and folders to no avail. I an upload the files to my OneDrive in the browser just fine.

Can anyone help me please? Thanks in advance!
