No textures upon import

[aliciagong]

Hi, I used Luma Ai to do all of my scans and used the "gaussian splatting" tab to export on their website for all of my files. I have cropped and color corrected them with another add-on in AE and exported them back to .ply files. But neither the edited .ply files nor the unedited ones' textures can be read when importing to Blender with your add-on enabled.
I usually get this error message: Python: Traceback (most recent call last):

File "/Users/aliciagong/Library/Application Support/Blender/3.4/scripts/addons/blender-addon/init.py", line 1177, in draw
row.prop(obj.modifiers["Geometry Nodes"].node_group.nodes.get("Boolean"), "boolean",
KeyError: 'bpy_prop_collection[key]: key "Geometry Nodes" not found'

I have imported these .ply files including the edited .ply file back to AE to double-check and the textures are present. I need them to work in Blender because I need to export them to .gltf format. Please help!
