Blender Version
Broken: version: 2.83.19, branch: master, commit date: 2022-02-01 20:05, hash: blender/blender@86c526d2c7
Worked: (newest version of Blender that worked as expected)

Addon Information
Name: BoltFactory (0, 4, 0)
Author: Aaron Keith

Short description of error

AttributeError Traceback (most recent call last)
C:\Program Files\Blender Foundation\Blender 2.83\2.83\scripts\addons\add_mesh_BoltFactory\Boltfactory.py in execute(self, context)
340 if bpy.context.mode == "OBJECT":
341 if context.selected_objects != - [ ] and context.active_object and \

342 ('Bolt' in context.active_object.data.keys()) and (self.change == True):
343 obj = context.active_object
344 oldmesh = obj.data

AttributeError: 'NoneType' object has no attribute 'keys'

Exact steps for others to reproduce the error

import bpy
bpy.ops.wm.read_homefile(app_template="")

bpy.ops.object.empty_add(type='PLAIN_AXES', align='CURSOR')
bpy.ops.preferences.addon_enable(module="add_mesh_BoltFactory")

make sure python get interrupted, other wise it will get another error, which is more common but more reasonable.

bpy.ops.mesh.bolt_add()

tried workaround*

When the active object is Empty, no matter it is plain axes or cone, try adding a bolt will cause the error.

so that add a new mesh before add bolt, and then unlink, and then remove, and then del it can avoid the problem.
