When trying to open an archive and read internal binary streams, for me it occurs, that the file-stream gets closed.
As a code-Snippet:

import zipfile

the second call results in the ValueError: seek of closed file

A quick and dirty solution (as an idea) is to change close() for the _SharedFile to run self.close() instead of self._close(findeobj) in the end (somehow around line 772).

Hopefully that helps

This seems to be a duplicate of issue40564 . Can you please add the python version you are using?

My used python Version is
Python 3.8.5 (tags/v3.8.5:580fbb0, Jul 20 2020, 15:57:54) [MSC v.1924 64 bit (AMD64)] on win32
Indead - this issue seems to be the same as 40564, but maybe my suggested solution is helpful?

Thanks, I am closing this in favor of issue40564. Jason has provided some possible approaches in issue40564 (msg375964) and would be helpful to follow the discussion there since it has more details.
