Leaf Aptus-ii 5 release switch broken

[NNN635658637796507798]

I currently have a Leaf Aptus-ii 5 (M645 mount) stuck on an a kapture group 4x5 adapter plate. Seems like the release switch/springs inside are not moving enough to release the back from the adapter. Any and all help is appreciated!

I can definitely see that the switch is moving the hooks but I don't think it's enough. If anyone has a diagram of what the internals of the switch looks like, it would be helpful.

Thanks in advance
