QEPCAD not working in python package of SageMath

[anirjoshi]

Steps To Reproduce

1. My machine is Mac M2 with the OS Ventura 13.4
2. I already have anaconda installed: conda --version prints conda 23.10.0
3. I used the command conda create -n sage sage python=3.9 to install sage in python as explained in installation guide
4. Then setting the environment using conda activate sage sets the appropriate environment.
5. The following program returns an error:

from sage.all import *
var('a,b,c,d,x,y,z')
qf = qepcad_formula
ellipse = Integer(3)*x**Integer(2) + Integer(2)*x*y + y**Integer(2) - x + y - Integer(7)
F = qf.exists(y, ellipse == Integer(0)); F
qepcad(F)    

Expected Behavior

There should be no error and a formula should be returned.

Actual Behavior

The error reported is

FWIW, this does not produce any error with the macOS binary package Sagemath-10-4.app. That app uses Python 3.12.
