3D freezes in some cases after adding and enabling Baked Lightmap

Steps to reproduce:

• Create a 3D project with wizard, Qt6.5 target
• Add another cube to scene
• Drag and drop Baked Lightmap from Components to cubeModel in Navigator
• Choose bakedLightmap in Navigator
• In Properties view, set Baked lightmap enabled to true and add some key
• -> 3D view freezes. if not, should freeze after clicking reset view button
• I was able to reproduce this with e.g cube + cube and sphere + sphere in scene, but not with e.g. cube + sphere
