FakeInventories Crash when clicking on an item :c (Pls Help)

[einsReplex]

Hey
I have this problem, I code with the API FakeInventories (the latest version)

And unfortunately I have this problem, so if you click on an item click for example (spawn)
The game crashes, if you are new joint you have teleported to the place you were

I hope you can help me

This is related to the client crash, that occures, when closing an inventory via packet.
