Creating Clickable Buttons on Windows Surface (Touchscreen)

You’re not displaying your stimuli. You will want to create the stimuli outside the loop, and just display them inside the loop via their respective draw() methods and win.flip().

text_2 = visual.TextStim(win=win, name='text_2',
    text='You will be presented with words or images to classify into categories using the buttons on the screen. \n \nTry to go as fast as possible while making as few mistakes as possible. \n',
    font='Arial',
    pos=[0, 0.1], height=0.1, wrapWidth=None, ori=0,
    color='white', colorSpace='rgb', opacity=1,
    depth=0.0)

polygon = visual.Rect(
    win=win, name='polygon',
    width=(0.4, 0.4)[0], height=(0.4, 0.4)[1],
    ori=0, pos=(0, -.5),
    lineWidth=1, lineColor=[1,1,1], lineColorSpace='rgb',
    fillColor=[1,1,1], fillColorSpace='rgb',
    opacity=1, depth=-1.0, interpolate=True)

text_4_Continue = visual.TextStim(win=win, name='text_4_Continue',
    text='Continue',
    font='Arial',
    pos=(0, -.5), height=0.1, wrapWidth=None, ori=0,
    color='black', colorSpace='rgb', opacity=1,
    depth=-2.0)

mouse = event.Mouse(win=win)
Pressed = False

while not Pressed:
    text_2.draw()
    polygon.draw()
    text_4.draw()
    win.flip()

    if mouse.isPressedIn(polygon):
        Pressed = True
        continueRoutine = False

I also simplified your while condition and the if block a bit.

You could even further simplify the while loop and get rid of the Pressed variable:

while True:  # Forever.
    text_2.draw()
    polygon.draw()
    text_4.draw()
    win.flip()

    if mouse.isPressedIn(polygon):
        continueRoutine = False
        break  # Exit the while loop.
