I could fix the same Errors with the new Input Sytem: []https://docs.unity3d.com/Packages/[email protected]/manual/Installation.html

Hi! I'd like to help resolve this issue, but I haven't been able to reproduce the problem. Can those who are encountering the error confirm that they've followed these steps or tell me what they've done differently?

1. Download and unzip (or clone) ml-agents-release_19
2. Using in the Unity Hub, use Unity 2021.2.X to Add the ML-Agents Example projects (ml-agents-release_19/Project folder)
3. In the Unity Editor with the Example project open, open the 3DBall scene from Assets/ML-Agents/Examples/3DBall/Scenes/

Two possible fixes to try in the meantime:

• Remove the version of ML-Agents you have from the Package Manager and the use Install From Disk and install both the com.unity.ml-agents and com.unity.ml-agents.extensions packages that are in ml-agents-release_19.
• Remove the PushBlockWithInput folder and PushBlockWithInput.meta file from \ml-agents-release_19\Project\Assets\ML-Agents\Examples
