Did you try using the browser Teams client as well, preferably via private session? Any specific error message?

@Vasil Michev That is the strange thing, there is no error, it tries to attach the file and then disappears. same in both Application and Browser and she has two different computers its same on both.

I have two users (out of 16000) that have reported the same issue

They can attach from Onedrive, but not from My Computer (or drag, drop)
Same behaviour in both Teams client and a Browser
Very odd
