3D viewport not showing in Godot 4.6.2 with GeForce 920M

Godot Version

Godot version: 4.6.2 stable GPU: NVIDIA GeForce 920M Driver: 425.31 Rendering: OpenGL Compatibility

The 3D viewport button does not appear in the editor. Only 2D, Script, Game, AssetLib buttons are visible. I added Camera3D and MeshInstance3D with BoxMesh but 3D view still doesn’t appear. Works fine in Godot 4.5.1 and 4.4.

func _ready() -> void:
    print("hello world")

Is it possible you disabled it? To completely hide the 3D editor tab for a 2D-only workflow, use Editor > Manage Editor Features and check 3D. After you do that you may have to click Make Current button or Reset the profile to Default
