Unable to attach documents to GMail

[oldchemist]

Hi

Until a few days ago I was able to attach documents to GMail messages by selecting the paperclip icon and double-clicking the document in my File list. What happens now is document title and file size appear at the bottom of the Gmail and the adjacent box fills with blue. All good so far, but after about one second the blue bar disappears leaving just the document title and file size and attempting to open the attachment reveals nothing there. Lenovo PC running Windows 10, Chrome browser. Attaching from Drive seems to be OK.

is the attachment too big?

[oldchemist]

File size is typically <20k - that should not be too big?

[oldchemist]

The biggest file I tried to attach is 522k

what anti virus re you running.
when was the last time you updated win10
when was the last time you updated chrome

do you have another browser, say like use windows edge,

Running Avast (free)
I thought that Win 10 updated automatically
I uninstalled and reloaded chrome last week after this issue arose.
I haven't tried another browser but will do so soon

thanks for taking the trouble to help
