当我使用cesium-unity-samples示例时，偶尔会报出Release of invalid GC handle. The handle is from a previous domain. The release operation is skipped.这个错误

Hi @masterofgongfu, welcome to the community!
I see you’ve posted a callstack for a bug. We usually need more information to figure out what’s actually happening. For example, what were you doing when you saw this message? Can you provide us with step-by-step instructions for reproducing it?
Once we have more information, we’ll be able to provide more informed support. Thank you!
使用的unity版本 unity 2022.3.17f1c1. 当我第一次打开项目并启动02_CesiumeMelboure时，很大概率会出现这个错误，我没有修改任何代码或执行任何操作。我猜想可能跟加载3D瓦片的texture有关，但我并没有找到证据来验证这一点。显卡使用的时 NVIDIA GeForce RTX 2060.而且每当我打开cesium-unity-samples时会占用我很高的GPU内存
Hi @masterofgongfu,
Thank you for the detailed information. I was able to see this error myself when entering / exiting Play mode in 02_CesiumMelbourne.
We keep track of bugs like these on Github, so I’ve written up some notes on this issue here. We need to investigate this more thoroughly, but we’ll be sure to update this thread when we make progress. Thank you again for your report, it’s very helpful!
