I came across that problem too. Here's a solution:
1. Pin File Explorer to taskbar
2. Create a standart shortcut to your folder on Desktop.
3. Move newly created shortcut to C:/Users/Username/AppData/Roaming/Microsoft/Internet Explorer/Quick Launch/User Pinned/TaskBar
4. Remove "File Explorer" shortcut
5. Name your shourtcut "File Explorer"
This is like replacing proper File Explorer shortcut with your folder shortcut.

If it's not a driver issue: You can also try, to deactivate the camera in device manager. After it, reactivate it again. If there really was an app using it, you've stolen it from that app, and it's possible now to get the handle on the camera.
Later you can try to use process manager to find the nasty app.
