It's never happened when engine is cold, only when the engine is warm.

I think I hear the flywheel rattle noise when it's happened.

My current setup is Exedy cluch kit with Exedy light flywheel with oem CSC https://www.ctd-germany.com/en/exedy-clutch-kit

Is it possible to have knock warning with light flywheel ?

Is the noise coming from the engine?

The following video is when I released the clutch pedal on 1st gear :
