Video [Q] Can't Record Video and Voice

When I try to record a video by clicking on the red button, the top panel with the symbols of setting, mode, flip camera, and flash disappear, and nothing has been recorded. It seems that the video recording function has been disabled because I've tried other apps that involve video recording and none are working.

The voice recording has the same issue. I can't record my voice, using voice command or voice and voice mate, or send out voice messages in different messenger-typed apps.

Did I disable something by accident?

Thanks.
