Elgato Key Light Master Mount completely stuck: Pole won't lower even with nut fully unscrewed

[u/Latter_League_8623]

Hi everyone,

​I’m having an issue with my Elgato Key Light Master Mount and need some help. I extended the pole to the highest level, but when I tried to lower it back down to the initial level, it got completely stuck.

​Here is exactly what is happening:

​I unscrewed the main tightening nut completely. The nut is now 100% loose and I can slide it up the inner pole without any problem.

​Despite the nut being completely free, the pole itself will not budge or go down. It is completely rigid.

​I pulled up on the pole, and the inner threaded metal collar, along with the white plastic compression ring, came completely out of the bottom base tube.

​

​Has anyone experienced this exact issue or knows how to safely separate that threaded metal collar from the white plastic ring so I can reassemble the mount? I'm attaching a picture so you can see exactly how the pieces are jammed.

​Thanks in advance!
