You're welcome. No worries about any typos, my mother tongue is also not English. But I guess with this setup we get along. If I cannot make any sense of a automatically translated sentence I will ask you again anyway.Also if you translate anything from my statements which does not make sense, I am happy to rephrase it.
That said, as Mitu checked already the config.txt file and it looks correct to me. Let's check if you have the file gpio-joystick.dtbo.
Excecute the next command on the Pi and provide the output here please:
find /boot/ -type f -iname "gpio-joystick.dtbo"
