dvc cannot import name 'exceptions' from 'cryptography.hazmat.bindings._rust'

[jamesdbrock]

Describe the issue

Problem with https://github.com/iterative/dvc which seems to effect all versions of dvc installed with poetry2nix.

On dvc push or dvc pull, fails with

ERROR: unexpected error - cannot import name 'exceptions' from 'cryptography.hazmat.bindings._rust' (unknown location)

Additional context

The error is happening from here in dvc’s dependency cryptography:

https://github.com/pyca/cryptography/blob/6b39f10598c1a291eaccdaa8b7bb2eedf4acab95/src/cryptography/exceptions.py#L9

cryptography override:
