Hi @DanielBaldrigue This error usually occurs when the Add Source button at the top of the RealSense Viewer's options side-panel has been used and a camera, such as the built-in RGB webcam in a laptop, has been unable to be accessed. Some RealSense users also use this button if their RealSense camera has not been automatically detected and listed in the side-panel.

Can you confirm whether this error occurred when the Add Source button was used, please?

Also, which RealSense camera model do you have?
