Issue with building a version of Blender 4.1.1 (GooEngine)

Question

I've been trying to build a version of Blender from its github. It kinda works i can open it fine and work on it. But in the cmd prompt, i get this message:

I can open it and work on it fine. The only thing that doesnt work for the moment is Eevee. The app just crashes once i open it. I didnt notice any other issues for now.

Would really appreaciate some insight on it. Ty.

Answer 1

The error messages indicate that Blender is attempting to load some add-ons (io_scene_fbx and io_scene_gltf2) but fails because it cannot import a specific function (poll_file_object_drop) from the bpy_extras.io_utils module.

If you just download Blender from https://blender.org/download it should include these which would fix your errors.
