Hello G A YUAVN,
Thank you for reaching out to Microsoft Q&A and informed us about the issue. Based on your description I believed that the 0xA00F4244 error is typically related to Windows Camera app failure. You can refer to these methods to tackle with this issue:
1. Reboot your PC:
- Sometimes a simple power cycle would resolve the issue.
2. Update Camera Drivers:
- Open Device Manager (Windows + X) > Cameras/Imaging devices > Right-Click your Webcam > Update driver > Search automatically > Windows will find available updates and install it.
3. Run a System File Check:
- Open Command Prompt and Run as Administrator then input this command one by one:
- sfc /scannow > Enter
- DISM /Online /Cleanup-Image /RestoreHealth > Enter (Do notice the space between the forward dash (/) in the command)
- Restart your PC
