Hello Dylan, Thank you for bringing this to our attention. We will look into it internally and see if we can find a solution. In the meantime, could you please tell me what version of Visual Studio 2022 Preview you are using? And are you able to get around the error by using a different version, such as Visual Studio 2019 or the latest version of Visual Studio 2022? ---

The latest version, it was just updated. I will try vs 2019 later today. I doubt that will fix it as the error is thrown in Unity itself in play mode ---

Hello Dylan, Thank you for your patience while we investigate this further. ARDK relies on many things under the hood that aren’t serialized and don’t function well with hot-reloading of assemblies while in play mode. Because of this, we recommend for scripts to always be edited/refreshed outside of play mode to prevent such potential issues. ---
