I kee getting a failure because of invalid structure. I have spent an hour combing the website looking for a solution I have redownloaded the zip file and I have downloaded the source code and the repo and the add-on. all are failing. I have reflashed my build on libreELEC and I have re-booted about 1000 times. I'm running Kodi 18.9, I'm running the default downloaded LibreELEC using the raspi imager, and I am using a raspi 4. please assist if you can.
