so i made a camera app for the hq camera but i cannot take any sort of pictures on my raspberry pi 4!
from guizero import App, PushButton
from picamera import PiCamera
camera = PiCamera()
app = App()
def preview():
camera.start_preview(fullscreen=False, window = (50,150,2048,1152))
button = PushButton(app, command=preview, text="preview")
def stop_preview():
camera.stop_preview()
button = PushButton(app, command=stop_preview, text="stop preview")
def shutter():
camera.capture('/home/pi/Desktop/image.jpg')
button = PushButton(app, command=shutter, text="shutter")
app.display()
but for some reason i get this error!
mmal: mmal_vc_port_enable: failed to enable port vc.ril.image_encode:out:0(JPEG): ENOMEM
mmal: mmal_port_enable: failed to enable port vc.ril.image_encode:out:0(JPEG)(0x1e258a0) (ENOMEM)

i also tried to make code to capture alone!
from picamera import PiCamera
from time import sleep
camera = PiCamera()
camera.start_preview()
sleep(5)
camera.capture('/home/pi/Desktop/image.jpg')
camera.stop_preview()
NOTE!: tried to get error code but i got stuck in preview after executing! but otherwise without preview i get this!
