[Bug Report] Animator Curve Serialize Error Reports "IntPtr is an unsupported type"

Description
I feel this is a bug as the error says to report it.

Replication
Steps to reproduce the behavior:

1. Create a scriptable object
2. Make a script that sends the scriptable object into an RPC
3. It should fail to compile and show errors.

Expected behavior
I expect it to warn me about it and show a better error, I had to hunt down what caused it and found it was the animation curves.

Screenshots
Error:

Scriptable Object:

I found it was a 3rd Party asset Dissonance.

I found it was a 3rd Party asset Dissonance.

Edit, It was not Dissonance, it was 100% the animation curves.

Yeah, IntPtr is not supported, it's unsafe.

The error is being properly displayed to a degree. It could use more information on how to isolate the type reviewed for serialization, as well a specific catch for IntPtr.

This will get done but perhaps not in 4.6.10

4.6.10 > Added insights to codegen which should point to at the very least the encapsulating type causing the issue.
