Robots don't show up in the plots

[AVSoriak]

Hi, I was creating a simple 3DOF robot using ETS notation and ERobot, then I tried to plot it following what is shown in this example, but there was no robot in the plot. I tried then to recreate the exact code shown in the example, and once again the robot didn't show up in the plot.
Here's the code I wrote:

import numpy as np
import matplotlib.pyplot as plt
import roboticstoolbox as rtb
import roboticstoolbox.robot.ET as ET
from spatialmath.base import *
from spatialmath import SE3, Twist3

l0 = 0.01; l1 = 0.4; l2 = 0.4; l3 = 0.4
e = ET.tz(l0)*ET.Rz()*ET.tz(l1)*ET.Ry()*ET.tx(l2)*ET.Ry()*ET.tx(l3)
print(e)

AleBot = rtb.robot.ERobot(e)
print(AleBot)

T = AleBot.fkine([0.5, 0.5, 0])
print(T)

sol = AleBot.ikine_LM(T)
print(sol)

pyplot = rtb.backends.PyPlot.PyPlot()
pyplot.launch()
pyplot.add(AleBot)
AleBot.q = sol.q
pyplot.step()
pyplot.hold()

OS: Win11 Pro
Python 3.12.3 via virtual environment using Anaconda
Robotics Toolbox ver. 1.1.1
matplotlib 3.9.1
swift-sim 1.1.0
spatialmath 1.1.14

Don't know if I'm doing something wrong or the problem comes from modules incompatibilities; I thank you all in advance for your help.
