It works fine in version 3.4.7

Please provide instructions to reproduce this error.

Two days with no response.

For future issue finders this is almost always because you have installed the wrong binary wheel on the platform you're attempting to run. You'll commonly run into this issue if you do things like try to bundle your local installation of cryptography on a mac and run it on Lambda, etc. We can't provide generic support for this sort of thing, but always install from wheels that you've confirmed work on your target platform.

I posted a pip command that will generate a correct bundle on #6391. You only have to adjust the Python version (--python flag).

Sorry for the late reply.
As @reaperhulk explained above, this was an issue with the lambda environment, super thanks @tiran for the documentation!
