Comment (by neirbowj):

 On `bigsur` `arm64` and with 2.7.1, I observed a substantially similar
 traceback in `py-cryptography` (35.0.0_3) after diagnosing a problem
 affecting the `ansible-vault` utility from `py-ansible`.

 {{{
 $ python -c "from cryptography.hazmat.backends import openssl"

 What I have managed to determine is that the proximate cause appears to be
 confusion between the version of OpenSSL `py-cryptography` was built
 against and which version it is being dynamically linked against. I came
 up with a short shell script to demonstrate the problem, which, on my
 system, affects 3.8, but not 3.7 nor 3.9.

 {{{
 # script
 TESTCODE="from cryptography.hazmat.backends import openssl"
 for i in 7 8 9; do
     echo "==> 3.${i}"
     port echo depof:py3${i}-cryptography | grep openssl
     SITEPKG=$(python3.${i} -c "import sys;print(sys.path[-1])")
     otool -L ${SITEPKG}/cryptography/hazmat/bindings/_openssl.abi3.so \
         | grep -oE "openssl[0-9]+"
     if python3.${i} -c "${TESTCODE}" 2> /dev/null; then
         echo succeeds
     else
         echo fails
     fi
 done
 }}}

 {{{
 # output
