Issue description

When i tried to bake the lightmap on the vulkan mobile backend, i i tried with the default primitive shapes, unwrapping the uv 2 and the common things when baking.

Then when i tried to bake, it resulted on an error where it says there's no lightmapper. I tried even on the forward + backend , but neither it worled.

And while this may be related to #77001 , in this case it isn't even trying to bake , it just throw an editor and doesn't bake light.

The error is this one
scene/3d/lightmap_gi.cpp:744 - Condition "lightmapper.is_null()" is true. Returning: BAKE_ERROR_NO_LIGHTMAPPER

Steps to reproduce

1 Open the project on your phone.

2 Try to bake the lightmap.

3 See the error in console.
