The following error occurred when I pressed the Play button in the Unity Editor while the Unity Editor was connected to the App Sim in the ML Hub, and it went into a paused state.

Hi Sadao,

Just to confirm, did you set up Universal Render Pipeline for this project as described in the setup guide? Additionally, what machine OS are you running this on?

Hi Kat,
I thought I had configured URP, but when I reconfigured URP again, the error did not occur and it worked correctly.

Thanks.
