Referencing noir_elgamal can execute test cases, but cannot run them

[Huang-Xinzhong]

Running nargo prove yields an error message
other error

What is the reason for this?

This is the executed code:

use dep::std;
use dep::std::ec::tecurve::affine::Point as Gaffine;
use dep::std::ec::tecurve::affine::Curve as AffineCurve;
