Hello @theghostbh, this seems to be an issue with the GoogleMobileAds DLL, and not with Newtonsoft.Json, given the error message from your stack trace: Mono.Linker.LinkerFatalErrorException: ILLink: error IL1005: GoogleMobileAds.Api.MobileAds.GetClientFactory(): Error processing method 'GoogleMobileAds.Api.MobileAds.GetClientFactory()' in assembly 'GoogleMobileAds.dll'

This could be because of the code stripping, so could you try adding a file named link.xml inside your Assets directory with the following content:

<linker>
    <assembly fullname="GoogleMobileAds" />
    <assembly fullname="GoogleMobileAds.dll" />
</linker>

You can find more help here: https://github.com/jilleJr/Newtonsoft.Json-for-Unity/wiki/Fix-AOT-using-link.xml
