Error code 0xA00F4244 NoCamerasAreAttached
The other day my integrated laptop webcam stopped working. When I opened the Windows native Camera App, I received the error code 0xA00F4244 NoCamerasAreAttached. I have an Asus Tuf Gaming F17 notebook running Windows 11 operating system. Typically in Device Manager, the camera showed up as USB2.0 HD UVC WebCam. I followed all the troubleshooting steps from the following Asus support site, https://www.asus.com/me-en/support/FAQ/109836/#Win11_A5 , with no luck. I also worked with Asus support but did not resolve the issue. After further investigation, I discovered the camera would disappear from the Device Manager when Microsoft Teams was open and running. When I quit the Teams application, the camera would re-appear in the list. I experienced this same behavior when using the Microsoft Teams Web Client. Is this related to a Microsoft Teams Update, or has this problem always existed? This is a new computer, and I do not have previous history with this issue.

Remedy/Solution:
(1.1) Mentioned by other contributors online and Microsoft Community.
Explanation:I encountered this issue with Laptop Camera (Lenovo S340, AMD Ryzen 5 3500U, 14") for several years, until I saw a post on Microsoft Community, with a solution to root cause on why laptop webcam was not detected.
Just by using 2 fingers (thumb, and 1st finger), by "pinching" or "pressing" area beside laptop camera, on external side and internal side of screen frame, the problem can be temporary solved (minutes, hours, days, weeks).
It could be a hardware issue of Laptop camera wiring or electrical contact issue (eg. loose contact). Very often, a laptop user may open the screen on either left side or right side, of screen, this may cause the screen frame to "Warp" (physical bending or twisting of an object). If user were to open laptop screen carefully, by opening laptop screen in the middle of screen, such issue could occur less. Screen frame "Warp" may cause laptop camera to encounter electrical contact issue, resulting in Webcam Not Detected, or Black Screen, etc.
Troubleshooting Windows software in this case may not solve Webcam Not Detected, Black Screen.
I had sent my laptop to Lenovo's service centre for 1 or 2 times for above problem, but still not solved even after reinstalling Windows 10 and other software. I heard similar issue for Asus laptop, and had informed a staff at their motherboard service centre on above remedy, during last visit.
Other Solution:
Buy a USB Webcam and connect to USB port on laptop, preferably a webcam from reputable brand driver software.
