IL2CPP error for method 'System.Void

Hi,
Just formatted my Mac and put a clean install of Catalina on and, then updated Unity to 2020.1.0f1 loaded my project that’s been working fine on Catalina before reinstalling and updating Unity, but now when I try and build I get this error.

IL2CPP error for method ‘System.Void Unity.GeneratedNetworkCode::_WriteArrayVector3_None(UnityEngine.Networking.NetworkWriter,UnityEngine.Vector3[ ])’ in assembly ‘/Users/kevin/Desktop/AR_Army_New/Temp/StagingArea/Data/Managed/Assembly-CSharp.dll’
Additional information: Hash code collision on value 09716D6B6B7159FFA4DDC4AAF2722973A3FF4FC8

Anyone know what’s gong on please ?

This looks like a bug on the Unity side - can you submit a bug report with a project that reproduces this?

Hi,
Don’t know what it was but opened a new project and imported scripts, models, prefabs ect from the old project and it’s all working fine now. The original project is 2.26gb.

Hi, I’ve found a new problem in my animator controllers about 50 percent or more are blank in the inspector, as you know if adding a new state you can see in the inspector the picture I’ve added, but on mine I can’t see anything on about 50 percent or more, and I have lots of state machine behaviour scripts on them I need to see, any idea what’s going on, and this is happening in a few projects I’ve imported into 2020.

PS. and SOME of the transition links to them are blank.
