Quick Answer
If the GemIQ Desktop App displays a recurring prompt to "open system camera settings," it usually indicates a problem with the camera's connection to your computer or a temporary issue with the app's cache. You can typically resolve this by checking your USB connection, clearing the app's cache, or reinstalling the app.

Before You Start
Ensure your GemCam Pro is connected to your computer via its USB cable.
Close any other applications that might be using a camera.
Steps
Follow these steps in order, from least to most disruptive. Stop when the issue is resolved.
Check the USB Connection
Unplug the USB cable from both the GemCam and your computer, then plug it back in securely.
If the error persists, try connecting the cable to a different USB port on your computer.
Clear the GemIQ Cache
Open GemIQ.
Navigate to the Help section in the menu.
Select Troubleshooting.
Click on Clear Cache and Local Data.
The app will log you out and restart. Sign back into your GemIQ account and check if the camera connects without the error.

The Troubleshooting menu in the GemIQ app, with an arrow pointing to the 'Clear Cache and Local Data' button. Reinstall GemIQ
Uninstall GemIQ from your computer.
Download and install the latest version from the official source for your operating system:
macOS: Apple App Store
Windows: Microsoft Store
Open the newly installed app, sign in, and connect your camera.
Expected Result
The "Could not open system camera settings" error message should no longer appear, and your GemCam should be recognized and ready to use within the GemIQ application.
If This Does Not Work
If the problem continues after trying all steps, the issue may be related to your computer's system-level camera permissions. Ensure that your operating system (Windows or macOS) is allowing apps to access the camera.
Common Mistakes
Using a damaged or third-party USB cable that does not support a stable data connection.
Not restarting GemIQ after clearing the cache.
Having other camera software (like Zoom, Skype, or Photo Booth) running in the background, which can prevent GemIQ from accessing the GemCam.
