ImportError: dlopen(/Users/kjellxvx/opt/anaconda3/envs/myenv/lib/python3.8/site-packages/fastecdsa/_ecdsa.cpython-38-darwin.so, 0x0002): symbol not found in flat namespace '___gmpz_add'

I get this error on my Silicon Mac... None of the suggested solution in the other issues helped. This error does occur since version 2.3.2, the lastest update.

Installing the previous version fixes the issue.

pip3 install fastecdsa==2.3.1

Version 2.3.1 was yanked and should not be used because the C extensions were not correctly built. See the pypi release page for reference. Is GMP installed on your machine (brew install gmp)?
