[Jubileus-ryz]

-python version: 3.9.9
-Kivy version: 2.1.0
-p4a version : 2023.1.28

It works well when building with p4a version 2022.12.20. But crash after updating to 2023.1.28

Having the same problem as you, I tried to fix it by adding 'requirements=typing_extensions'.

class QRcodeImage(Image):

    def qrcodeImage(self, data: str):
        import qrcode
        from io import BytesIO
        from kivy.core.image import Image as CoreImage
        qr = qrcode.QRCode(version=1, box_size=64)
        qr.add_data(data)
        qr.make(fit=True)
        png = BytesIO()
        qrPillow = qr.make_image(fill='black', back_color='white')
        qrPillow.save(png, format='png')  # save pillow image to memory buffer
        png.seek(0)
        return CoreImage(BytesIO(png.read()), ext='png')  # ram buffer to image

Does it look like the Image class now requires pypng and typing_extensions to be declared as explicit requirements?
