Don't sure about this particular library, but actually the fix helped with WebGL build and similar issue

Your link.xml solution, not only doesn't work as it makes the app crash instead of just showing the error.

The link.xml workaround does not work.
Please can this bug be re-opened? This has negatively impacted user experience and has not been fixed for years. This bug should be prioritised.

Why is this marked as Won't Fix?!
This should be fixed, it has severely negatively impacted my experience in using Unity Pro.

I had the same issue on Android. The problem was not newtonsoft, but the fact that i was using the "dynamic" data type. Changing the type from dynamic to object solved the issue.

After struggling with this same issue for a while I successfully migrated my project to a new JSON plugin and I can now compile using IL2CPP on Android and my JSON is working properly.

I'm still getting this in 2019.3, and the link.xml fix isn't working.

- NullReferenceException is thrown when changing the Inspector preview selection
Resolution Note:
For the time bring there is a work around for this issue. Include the following link.xml file in the project:
<linker>
<assembly fullname="System.Core">
<type fullname="System.Linq.Expressions.Interpreter.LightLambda" preserve="all" />
</assembly>
</linker>
Once the class libraries Unity uses from Mono are updated, this work around will no longer be necessary.
