Why do I only hear audio but see a black screen when a video plays in VRChat worlds?

This specific issue often points to a problem with video rendering rather than audio playback. Common causes include outdated or corrupted graphics drivers, conflicts with hardware acceleration, or issues with VRChat's embedded Chromium-based browser (Coherent UI). Ensure your GPU drivers are fully updated. You might also try disabling any overlay software that could interfere with rendering. Sometimes, a full reinstall of VRChat or ensuring your Windows Media Feature Pack is installed (for N/KN versions of Windows) can help.
