Thanks, I reverted this commit https://github.com/platformio/platformio-core/commit/39494d18bf66cf24ae9e7b6db6c2b638985c6837

Seems it fixes the original issue.

Could you try manually installing cryptography?

source ~/.platformio/penv/bin/activate
pip install "cryptography==3.3.2"

Does it work now?
