Hi! Based on the message shown, Windows is not detecting a Windows Hello–compatible infrared (IR) camera. Please first go to Settings > Privacy & security > Camera and confirm camera access is enabled, then run Settings > System > Troubleshoot > Other troubleshooters > Camera.
After that, open Device Manager, expand Cameras and Biometric devices, and update or uninstall/reinstall the camera driver, then restart the PC.
If the issue started recently, also check Windows Update > Advanced options > Optional updates and install any camera, chipset, or firmware updates available, because those can restore Windows Hello functionality after a driver change.
