Sagemath refuses to load singular curve

I know that this below Elliptic curve is singular at (23796,0)

F = GF(23981)
E = EllipticCurve(F,[0, 0, 0, 17230, 22699])

Since

fx=3x2+17230=0(modp) and vanishes at x=185,23796 and (185,0) not on the curve.

fy=2y=0(modp) and vanishes at y=0

I'm trying to define this curve to plot but SageMath gives the error;

ArithmeticError: invariants (0, 0, 0, 17230, 22699) define a singular curve

How can I plot this curve?
