Issue Description

Hello guys,

Code and error below. Do you guys knows how can I handle this kind of error (when setting options), avoiding the crash?

Thanks.

Code (C#):

        Pipe = new Pipeline();  
        Config = new Config();

        Config.EnableStream(Stream.Color, 1280, 720, Format.Rgba8, 30);
        Config.EnableStream(Stream.Infrared, 1280, 720, Format.Y8, 30);

        PipelineProfile profile = Pipe.Start(Config);

        Sensor sensorIR = profile.Device.Sensors[0];
        Sensor sensorColor = profile.Device.Sensors[1];

        foreach (var opt in sensorIR.Options)
        {
                if (opt.Supported)
                {
                        if (opt.Key == Option.EmitterEnabled)
                        {
                                opt.Value = 0f;
                        }
                        if (opt.Key == Option.EnableAutoExposure)
                        {
                                opt.Value = 1f; // -------> Error happens at this line
                        }
                }
        }

Just one fact that might not be related. When I try to use RealSense Viewer after this problem happens, the Viewer gets "stuck": I can't access anything (Add Source, On/Off cameras, 2D/3D, nothing). Don't know if it was a consequence of the code, or the camera was in a weird state before (note: it was the first usage after booting computer, so the camera wasn't being used before).

Hi @easchimidt,

What's your D435 firmware version? Can you upgrade it to the latest version. I don't observe this issue based on a quick modified test based on the C# example "cs-tutorial-2-capture".

Hi @easchimidt,

Any update? Do you still observe this issue in the latest librealsense?

Hi. Sorry for the late reply. I've tried with the latest firmware, and the bug isn't happening anymore when disabling the emmiter.

Thanks for the help!
