Google drive recently patched the copy feature. If I remember correctly they only let 1TB be downloaded for a specific file in 24 hours.
What a bummer! It appears none of the usual Drive download workarounds are functioning for me either. I can always wait a bit more, hopefully in a week or so the download rush has subsided! 😕
I found that if you go a folder up and just download the entire containing folder, it’ll work.
