What: Components are now accessed via `getattr` instead of via dictionary key when copying components from one object to another and property_unset is used to remove components instead of deleting them directly. Why: Blender 5.0 no longer allows access to `bpy.props` properties (which is what the components technically are) via dictionary key or directly deleting them. Notes: It's unclear which cases of dictionary key access are affected by the changes in Blender 5.0, e.g. properties within a `PropertyGroup` seem to act the same as previously (accessible via dictionary key after they have been set at least once). The replacements for dictionary key access and deleting properties work in previous versions of Blender, so support for previous versions remains the same.

I think we should also add 5.0 to the CI test versions. |

There was a problem hiding this comment.
I have tested the PR in Blender 5.0 on Linux and it works like a charm, no errors triggered when copying or removing a component.

What?
Prevents Python errors when copying components from one object to another, and when removing components in Blender 5.0.
Why?
To allow components to be copied or removed successfully in Blender 5.0, the same as in previous versions.
Examples
N/A (this prevents Python errors, so the only thing changed should be that no errors pop up in Blender 5.0 when copying or deleting components).
How to test
Documentation of functionality
No changes to functionality/behaviour.
Limitations
Only tested in Linux, but otherwise there are no known limitations.
UPDATE: this doesn't address the issues with the Loop Animation component that were found after this PR was opened.
Alternatives considered
None.
Open questions
Does this work in Windows/Mac?
