System Information
Operating system: Windows 10
Graphics card: RTX 3080TI

Blender Version
Broken: 4.1
Worked: (newest version of Blender that worked as expected)

Short description of error
When applying tranforms via the search panel (f3 > apply all transforms) or via Object > Apply > All Transforms to an empty object (e.g. plain axis) the addon magic_uv will throw following python error:
Python: Traceback (most recent call last): File "A:\Programme\Windows\BlenderFoundation\4.1\4.1\scripts\addons\magic_uv\op\copy_paste_uv_object.py", line 149, in draw uv_maps = compat.get_object_uv_layers(obj).keys() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "A:\Programme\Windows\BlenderFoundation\4.1\4.1\scripts\addons\magic_uv\utils\compatibility.py", line 120, in get_object_uv_layers return obj.data.uv_layers ^^^^^^^^^^^^^^^^^^ AttributeError: 'NoneType' object has no attribute 'uv_layers'

When the addon magic_uv is disabled this error does not occur.
When applying transforms to an actual mesh this error does not occur.
When pressing ctrl + a > All transforms this error does not occur.
It doesn't matter what transform gets applied.
The error happens for all non-mesh object types, like empties or path based object with no actual mesh and thus no uv layers.
It has no effect on the applying transforms, it's just to some extent annoying to see some error message unrelated to the operation the user is performing.

Exact steps for others to reproduce the error
Based on the default startup .blend file.

Make sure the addon magic_uv is enabled and operational
Open the info editor to not miss the logged error in case it won't get displayed in the bottom bar.
Create an empty object (e.g. plain Axis)
With the empty selected: In the header of the 3d Viewport press Object > Apply > All Transforms
the Attribute error should now be logged in the info editor
