Seems related with pypa/setuptools#3849 (comment)

[KlemenKobau]

I think this is related to the package using pyyaml 5.4.1 which uses a now invalid configuration for the license in setup.cfg.

Link: yaml/pyyaml#724

The version of keycloak-client on main uses pyyaml 6.0.1 which fixes this. Is the code on main stable? Could you release it as a new tag?

I've been the same problem here with a fresh installation:
