What's the issue you encountered?

As I brought up in Issue #3291, when taking lots of Scene images as one would do for Reinforcement Learning, Unreal Engine generates a breakpoint inside of RenderRequest.cpp and crashes the simulator.

Settings

How can the issue be reproduced?

1. Download and Build AirSim and the default Blocks environment.
2. Change the image request in the init function of drone_env.py from self.image_request = airsim.ImageRequest( 3, airsim.ImageType.DepthPerspective, True, False ) to self.image_request = airsim.ImageRequest( 3, airsim.ImageType.Scene, True, False )
3. Inside of transform_obs, change img2d = np.reshape(img1d, (responses[0].height, responses[0].width)) to img2d = np.reshape(img1d, (responses[0].height, responses[0].width, 3))
4. Inside of transform_obs, change return im_final.reshape([84, 84, 1]) to return im_final.reshape([84, 84, 3])
5. Start Unreal Engine and run dqn_drone.py. Wait for a minute or two for the images to be taken and processed.
