ClientSim cannot call VRCImageDownloader.DownloadImage() from Udonsharp.
An error occurs when assigning a U# script for receiving events to the argument that passes the IUdonEventReceiver type.
I tried assigning null, but the result was the same.
This error seems to occur in VRCSDK 3.10.2-beta.1.
When I perform a test build and run it from the Oβ client, the image loads successfully without any errors.
