I mounted my disk this way:
from google.colab import drive
drive.mount('/content/drive', force_remount=True)
And I get access to all the files on the disk except for one: MyDataset.zip
If I try to copy it this way:
copy_cmd = "/content/drive/My\ Drive/MyDataset.zip /content/MyDataset"
!cp $copy_cmd
He writes an error:
cp: error reading '/content/drive/My Drive/MyDataset.zip': Operation canceled
If I try to download it via the colab file browser, it writes this error:
Error
Download failed

In this case, cp and file browser downloads work with any other files on the mounted disk.

What's wrong?
Well, I solved the problem, this is of course a crutch, but I had to split the archive into parts, change its format to rar (zip sucks with multi-volume and does not support modern encryption), and encrypt it, after that Google no longer blocks the transfer
The most interesting thing is that MyDataset.zip was downloaded 2 times, and then suddenly stopped, and even after 2 days, nothing changed, either in the code or in the archive.
Google can block unwanted files without warning.
