Additional context
Add any other context about the problem here.
The sqlalchemy package recently released their 2.0.0 version. MFA did not freeze its dependency version, and the incompatibility of this new major version breaks all commands of MFA, even the mfa version.
Simply pip install sqlalchemy==1.4.46 will solve this problem.
