Windows 10 Camera issu

Chrome permissions set to allow. Mic works but Jitsi thinks camera permission denied. If change to “ask”, Jitsi asks for mic access but not for camera. Setting camera permission to “allow” manually does not change result. This problem appeared a couple of weeks ago for no apparent reason.

Got around problem by switching to Firefox, but now Jitsi stopped responding to mic several days ago. All permissions are enabled and Jitsi website thinks mic is enabled, but doesn’t respond to it. Mute/unmute appears to respond, but when unmuted no response to sounds. Also, no response to drop down next to mute button on Firefox, but there is a normal response to this on Chrome.
