Let me get this right:

• You keep making outrageous claims yet you have shown no evidence supporting it.
• You missed some important information, such as that you tried full un/reinstall.
• You expect different results from a random repackaged RPM, even though that RPM was originally installed from the same source you claim did not work for you.
• You are happy to try random dconf commands, risking screwing up your system even more, rather than trying to think back what other random changes you had done to your system to screw it up in the first place.
• We still do not know whether your LED works in other applications.

Mind boggles.

BTW, the light does not depend on whether you are recording or not. It comes on the moment you tap the icon and off when you tap the other one or close Camera. If you closed Camera with the light on, it goes off but turns back on the next time you start Camera again.
