Since basic troubleshooting was already done, use this order:
- Check whether Windows can see the camera at all.
- If it is an external camera, reconnect it firmly and try a different USB port.
- If it is built in, open Device Manager and look under Cameras, Imaging devices, or Sound, video and game controllers.
- If the camera is missing, in Device Manager select Action > Scan for hardware changes.
- Check Windows updates and optional driver updates.
- Go to Start > Settings > Windows Update > Check for updates.
- If nothing appears, open Advanced options > Optional updates and install any camera driver updates.
- Restart the PC after installing updates.
- Test in the built-in Camera app.
- Open Start > Camera.
- If it works there, the problem is with the other app.
- If it still shows the covered-camera message or timeout, continue with driver repair.
- Reinstall the camera driver.
- Open Device Manager.
- Right-click the camera device > Uninstall device.
- If available, check Delete the driver software for this device.
- Select OK.
- In Device Manager, select Action > Scan for hardware changes.
- Restart the PC and test the Camera app again.
- If the problem started after an update, roll back the driver.
- In Device Manager, right-click the camera > Properties > Driver tab.
- Select Roll Back Driver if available, then restart and test again.
- Switch the webcam to the built-in UVC driver.
- This requires admin rights.
- In Device Manager, right-click the webcam > Update driver.
- Select Browse my computer for drivers.
- Select Let me pick from a list of available drivers on my computer.
- Choose USB Video Device > Next.
- Restart and test again.
- Note: this can reduce camera-specific features such as Windows Hello face recognition if the manufacturer driver provided them.
- Check antivirus or firewall camera blocking.
- Some security software can block camera access.
- Temporarily disable that protection in the antivirus or firewall app and test the camera.
- If the camera is old, check compatibility.
- In Device Manager > camera Properties > Driver > Driver Details, if a file name includes stream.sys, the camera was designed before Windows 7 and needs replacement with a newer camera.
The screenshots showing “Your camera might be covered” and 0xA00F4293<VideoCaptureStartTimeout> fit a driver or device-detection problem, so the most useful next steps are reinstalling the driver, rolling it back if this began after an update, and then switching to USB Video Device if reinstall does not help.
