The issue arises when the user tries to use the system/device camera in Discord but the camera does not work (sometimes the affected user just sees a black or green screen). The other party cannot see the user but just a black screen with a never-ending loading screen. The issue is reported on all major operating systems (Windows, Mac, Linux, Android, iOS, etc.) with all the variants of cameras (built-in or external). Before moving on with the solutions to fix the Discord camera problem, restart your device/system to rule out any temporary glitch. Moreover, check if your camera is working fine in other applications (especially the default camera application). Furthermore, the privacy settings of your device/system allow the usage of cameras in Discord.
Solution 1: Update the OS of Your System/Device to the Latest Build
The OS of your device/system is regularly updated to add new features to it and patch its known bugs. You may encounter the issue at hand if the OS of your device/system is outdated which can create incompatibility between the camera and OS. In this case, updating the OS of your system to the latest build may solve the problem. For elucidation, we will discuss how to update the OS of Windows; you may follow the instructions pertinent to the OS of your device/system.
Solution 2: Rearrange Your USB Devices (USB Camera Only)
Your system’s camera might not work if your USB ports are overcrowded as every USB port can handle a limited number of endpoints and if the number of endpoints exceeds what the USB can handle, it may lead to the error under discussion (some users encountered the error message of Not enough USB controller resources). In this case, rearranging the USB devices may solve the problem.
Solution 3: Launch the Discord Application with Administrator Privileges
With every new version of Windows, Microsoft is greatly enhancing the safety/security features and one such feature is the requirement of administrative privileges to access protected Windows resources (like the mic, camera, etc.). In this context, launching the Discord application with administrative privileges may solve the problem.
Solution 4: Reinstall the Camera Driver
Your camera might not work in Discord if the camera driver is not properly configured, outdated (that may cause compatibility issues between the camera and Discord), or is corrupt. In this scenario, updating or reinstalling the driver may solve the problem.
Solution 5: Change Your Default Camera
You may fail to use your camera in Discord if it is set as the default camera because it can be used in the background by some other application and may not be available to Discord. In this case, changing your default camera to another one (that you do not want to use) may solve the problem.
Solution 6: Reinstall the Discord Application
If none of the solutions was effective in resolving the issue, then the issue could be a result of a corrupt installation of the Discord application. In this case, reinstalling the Discord application may solve the problem. For elucidation, we will discuss how to reinstall Discord on a Windows PC. If the issue pursues, either reset your system/device to the factory defaults or use Discord in a web browser till the issue is sorted out.
