You probably have to patch that declaration to add "noexcept".  See
https://src.fedoraproject.org/rpms/python-pari-jupyter/blob/rawhide/f/python-pari-jupyter-cython3.patch
for an example.  If that is the issue, see
https://cython.readthedocs.io/en/latest/src/userguide/migrating_to_cy30.html#exception-values-and-noexcept
for more information.
