This is currently an issue with platformio's distribution of esp-idf. You can either enable the native feature of esp-idf-sys to use cmake instead of pio. Alternatively, if you'd like to stick with pio the following commands should work.

source ~/.platformio/penv/bin/activate
pip install "cryptography<4"
