PyInstaller Executable Does Nothing

[pdihawk]

Here is my code:

from guizero import App, Box, Text
from datetime import date

def get_jdate():
    today = date.today()
    day = today.strftime("%d")
    month = today.strftime("%m")
    year = today.strftime("%y")
    julianday = today.strftime("%j")
    JDate.value = julianday+year
    print("Got Jdate")
    app.update()

appWidth = 200
appHeight = 100
app = App(title="", width=appWidth, height=appHeight, bg="#AFAFAF")
JLable = Text(app, size=15, text="Julian Date")
JDate = Text(app, size=40)
get_jdate()
app.repeat(900000, get_jdate)

app.display()

What exactly do you mean by the full traceback? :)
