How can I solve AttributeError: '__RestrictContext' object has no attribute 'scene' problem?

[Stern-Hayat]

Hello.

I installed your wonderful concept add-ons on my Mac, and I tried [Preferences] -> checked [Mesh: Building Tools].
Then 'AttributeError: '__RestrictContext' object has no attribute 'scene' error occurs and I cannot activate add-ons.

How can I solve the problem?

blender version: 3.0.0
add-on version: 1.0.9

Thank you.

Try using the zip from the releases rather than the master branch. I will try to get a fix out today.
