[AlexisQen]

When i installed OBS for the first time it works correctly but then my camera stopped working and it showed a OBS camera error icon, and then when i usec WhatsApp desktop version or Zoom to use the camera it showed the same image. I uninstalled OBS and then my camera started to work in whatsapp and zoom. Someone please help me :C
