System information

Godot v4.1.stable - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1050 (NVIDIA; 31.0.15.3667) - Intel(R) Core(TM) i5-8300H CPU @ 2.30GHz (8 Threads)

Issue description

Create an export category/group/subgroup with a name that coincides with a base class and then try to instantiate one instance of that class.

Steps to reproduce

Just this:

extends Control

@export_category("Label")
#@export_group("Label")
#@export_subgroup("Label")
@export var text: String

var label: Label


func _ready():
	label = Label.new()
	label.text = text

When I run the code, I get:

Invalid call. Nonexistent function 'new' in base 'Nil'.

My temporal solution is to do @export_category("Label_") or similar.

• Duplicate of Invalid call. Nonexistent function 'new' in base 'Nil'. if you use @export_group with same class name #73843.
• Fixed by GDScript: Fix conflict between property and group names #78254 for future 4.2.

Thanks for reporting the bug nonetheless!
