I am having issues creating a custom "Add Mesh" pie menu, Ive made a script, sampling from a number of different sources of code, that functions well enough from the text editor, However when i try to install it as an addon and enable it i get this error.
Which through reading a number of posts I believe I understand the "why" of why its happening, but my limited Python knowledge is hindering my ability to fix it. I believe the issue comes up at line 201 or so where i am trying to create a custom operator to assign different meshes with custom properties. At least thats what i understand it to be.
Ive tried altering the order of the class-list to change registration order, creating a class in itself for assigning the "type= bpy.props etc" attribute and registering that outside of the normal class list. Ive tried throwing an @classmethod or two in there (like i REALLY know what that's doing) but this is all mostly flailing in the dark and trying stuff i find in other stackexchange answers but nothing so far is helping.
I would greatly appreciate any help offered! Thank you in advance for your time.

Solutions I have tried, to the extent of my knowledge. This one being the main devlog post detailing the error, Which i cant figure how to use in my own script, but am sure would fix the issue.
As well as these other ones, as well as several other minor attempts.
