Hello. Hope you are doing well. Thank you for the great job! while loading the Windows Scene I get these Errors:
The same field name is serialized multiple times in the class or its parent class. This is not supported: Base(MonoBehaviour) _object

The same field name is serialized multiple times in the class or its parent class. This is not supported: Base(MonoBehaviour) _handObject

'HandManager' is missing the class attribute 'ExtensionOfNativeClass'!

Would you please help me fix them? I have attached a screen shot of the scene
Thank you for any prospective answers!

Hello AmirrezaDaghighi1! Thank you for visiting our project Arvis.

You can just ignore that exception because it does not affect process execution. Arvis is still in progress so we are fixing some problems like this.

After updating, Arvis will run on Android platform. You will be able to use more stable version of this project. Good luck!
