Firefox camera access causes the webcam to stop working system-wide until reboot

I am using Windows 11 (Version 23H2, fully updated) and a Logitech C920 USB webcam. Before testing in Firefox, the camera works perfectly in Chrome, including Google Meet, as well as in the Windows Camera app. When Firefox is opened but does not access the camera, everything works normally in the system. When I allow Firefox to access the camera on a website requesting permission, the webcam initially shows a working preview inside Firefox. But, after the preview, the camera stops working in Firefox and shows a message asking me to allow devices again, even though permission has already been granted. After I test the camera in Firefox and then close it, the webcam stops working system-wide. Chrome then reports that the camera is in use or unavailable, and the Windows Camera app also stops working until a reboot. In addition, when this issue occurs, the Windows Settings page Privacy & Security → Camera loads continuously without finishing anything, but the contents are visible and clickable while it keeps loading. I have to reboot the computer to restore normal camera functionality. I wanted to use Firefox as my only browser, but this situation stops me from doing so.
