ONNX Runtime v1.16.2 crashes with Unity IDE

[Storm-Develop]

Describe the issue

Starting from ONNX Runtime v1.15.0 Unity crashes upon trying to create inference session from the .onnx model.

Note: ONNX Runtime v1.14.1 works as expected.

It gives out of memory exception.

It seems like changes introduced at v1.15.0 break for Unity environment. It's targeting .NET Standard 2.1

To reproduce

Have UNITY IDE v 2022.3.3f1 or any other Unity 2022 version

Import Microsoft.ML.OnnxRuntime & Microsoft.ML.OnnxRuntime.Managed packages in the project

The import could be made by manually copying .NET Standard Microsoft.ML.OnnxRuntime DLL Or use Nuget Manager ( https://github.com/GlitchEnzo/NuGetForUnity) to install the Onnx packages

Try to create a session using onnx model. `using var session = new InferenceSession(path);

Run in the Unity editor in the playback mode or as Unity test.

Well, the issue is still not resolved, any version after the v1.14.1 causes the crash in the Unity Editor.
