iMac 13.2 and some opencore bugs

Hi, I tried to install MacOS Big Sur, Monterey, Ventura and Sonoma on my iMac 13.2 from 2013 and every time I have the same bug when I boot on the installation usb key there is an error with the installer: The copy of the install macOS application (the macOS I'm trying to install) is damaged and can't be used to install macOS. I tried everything I saw on the internet but nothing works if anyone knows the answer please answer me
