this is the new error
This is because when you start the app libil2cpp is not loaded. You should start the game then load frida script
Frida version 15.2.2
frida-server-15.0.7-android-x86_64
Happens to me when I run this command
Frida version 15.2.2
frida -U -f br.com.brainweb.name -l jsInjection.js --no-pause
