Null Reference error in Desktop build of WalletConnectUnity Demo scene

[yozdev]

Hello Team,

This is related to the WalletConnectUnity version from https://github.com/WalletConnect/WalletConnectUnity/tree/2.0.

I'm using Unity version 2021.3.23f1

When I run the SimpleUnityDapp demo scene in Unity Editor, it runs fine without any errors.

However, when I make a Windows build and run it, it gives the following error after I choose a chain from the list and press Connect button

Console Log Error :

NullReferenceException: Object reference not set to an instance of an object.

Please help with this. I do not understand why issue is coming in build only.

Is anyone else facing this issue ?
