Photo Booth Video Not Working Macbook Pro M1 chip 2021

Video not working for macbook pro m1 chip. On several occasions, it 'records' a completely black screen (green light camera is on, Facetime works fine) or takes stills, and the recording clock is beyond wrong. When it does 'take' something, it is a series of still photos, and the clock reads "51: 20: 03: 30" for less than 10 seconds of 'footage.' So the timing clock is wrong, it's not taking video, and for the lighting in the room, the image is incredibly grainy. Along with countless other problems with this computer, disappointed in having this issue on top of the rest. I have the latest update. Have restarted. Still an issue. Video not working on Photo Booth even though camera is on and Facetime works fine.
