Error when attempting to install relay server on Unity 2020

[karolenn]

Hello!

I installed the Unity MCP through the git URL in the Package manager in Unity 2020: https://github.com/codemaestroai/advanced-unity-mcp.git?path=Unity2020_2022

It installed successfully. After opening the MCP Dashboard it throws error when attempting to install the relay server:

[CODE_MAESTRO_UNITY_MCP] Installation failed: Failure has occurred while loading a type.

@karolenn sorry for taking such long time to actually give you a response on this. We were working really hard on resolving issues around this tool. Please try the latest version that was just release v1.2.16 and let us know if the issue persists.

Hi @pavel-shchelkun-ilogos. I tried it again installing it through the package manager with the following link:
https://github.com/codemaestroai/advanced-unity-mcp.git?path=Unity2020_2022

I then get error:

I am using Unity 2020.3.14f1. I can open the MCP Dashboard but when I click "Install Now" for the relay server I get the following error:

Got any ideas how I might fix this?
