graphenediscoverer4 Failed to extract native libraries, res=-113
This sounds like maybe the APK was built for a different architecture than the device -- for example, it's a 32-bit ARM binary being installed on a 64-bit device.
Specifying the URL of the APK that didn't install and the model of the device that the install failed on would be good.
Also it would be good to specify the GrapheneOS build string from Settings, About phone, Build number.
