Hello
The error you're encountering, 0xA00F4293 <VideoCaptureStartTimeout>, typically indicates an issue with the camera not being able to start capturing video within a certain timeframe.
Given that you've already tried various troubleshooting steps, here are a few additional suggestions:
Check Camera Permissions: Make sure that the Camera app has the necessary permissions to access your camera. You can do this by going to Settings > Privacy > Camera, and ensuring that the Camera access for this device is turned on.
Update Camera Drivers: Sometimes, outdated or corrupt camera drivers can cause issues with the Camera app. Try updating your camera drivers to the latest version. You can usually find these on the HP support website for your specific laptop model.
Check for BIOS Update: Occasionally, firmware or BIOS updates can resolve hardware-related issues. Check if there's a BIOS update available for your HP Pro x360 435 Notebook PC and install it if there is.
Try a Different Camera App: As a temporary workaround, you could try using a different camera app to see if the issue persists. There are several third-party camera apps available in the Microsoft Store that you could test.
Check for Hardware Issues: If none of the software-related troubleshooting steps resolve the issue, it's possible there could be a hardware problem with the camera itself. You might consider contacting HP support for further assistance or possibly having the camera hardware inspected.
