What's the issue you encountered?

When i call the python api to get static mesh, it gets stuck in GDynamicRHI->RHILockBuffer(*this, Buffer, Offset, SizeRHI, LockMode) and Raised Segmentation fault error! The log message indicates "Assertion failed: GraphicsContext [File:Runtime/RHI/Public/RHICommandList.h] [Line: 755] There is no active graphics context on this command list. There may be a missing call to SwitchPipeline()."

Settings

How can the issue be reproduced?

1. Run airsim in quadrotor simulation mode;
2. Call python API client.simGetMeshPositionVertexBuffers();
