VSCode suggestions work but inproperly

[oblique burrow]

It suggests variables from other scripts that aren't accessible and some random variables/methods that godot never shows.

Does anybody have any idea how to fix this :D

I honestly have no idea why. It could be that the extension is misconfigured.
But it is usually recommended to use Godot's script editor.
It has more relevant features and is better integrated.
