Strange error while using Kivy-- Process finished with exit code -1073741819 (0xC0000005)

[Franco Nero]

Hi All,

I've just started using Kivy.  I am using Python 3.7 and Kivy 1.10.1 on a windows 10 machine. I was just following one of the available tutorials on Youtube. Then I decided to tweak the script and am getting a really weird error...

the problem is, I've created two screens and a button on each screen to switch the screens.... Then I decided to add another button to one of the screens to do something else... But when I did that and ran the code, I received the error in the subject line. I thought it was Pycharm or Python so I googled the issue and tried to change all sort of things to no avail... I ran the program from the console and same thing happened so it isn't Pycharm...

Finally I started one by one to remove Kivy code lines and as soon as I removed the text property for the second button, the program started to work and the problem went away... However, as soon as I add the property back, I get the same error!

Below is the py and the Kivy codes:

Py:

import kivy
from kivy.app import App
kivy.require('1.10.1') # replace with your current kivy version !
#from kivy.uix.floatlayout import FloatLayout
#from kivy.uix.label import Label
#from kivy.uix.widget import Widget
#from kivy.graphics import Line
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen, FadeTransition
from kivy.uix.widget import Widget
from kivy.graphics import Line

class Painter(Widget):
    def on_touch_down(self, touch):
        with self.canvas:
            touch.ud["Line"]= Line(points=(touch.x,touch.y))

    def on_touch_move(self, touch):
        touch.ud["Line"].points +=(touch.x,touch.y)

class MainScreen(Screen):
    pass

class AnotherScreen(Screen):
    pass

class ScreenManagement(ScreenManager):
    pass

presentation = Builder.load_file("main.kv")
class MainApp(App):

    def build(self):
        return presentation

if __name__ == '__main__':
    MainApp().run()

main.kivy

#: import FadeTransition kivy.uix.screenmanager.FadeTransition

ScreenManagement:
    transition: FadeTransition()
    MainScreen:
    AnotherScreen:

<Button>:
    font_size:40
    color: 0,0,1,1
    size_hint: 0.3, 0.2

<MainScreen>:
    name: "Main"
    Button:
        on_release: app.root.current = "Other"
        text: "Next Screen"
        pos_hint:{"right":1, 'top':1}


<AnotherScreen>:
    name: "Other"
    FloatLayout:
        Painter
        Button:
            on_release: app.root.current = "Main"
            pos_hint:{"right":1, 'top':1}
            text: "Go Back"
        Button:
            pos_hint:{"right":1, 'top':0.5}
            on_release: app.root.current = "Main"
            text: "Return"

So, if you remove either of the text properties in AnotherScreen, the program works!

Any help is appreciated...

Thanks
