crash when reloading addon with popup is open

[TheRealSyler]

i don't think that this is a big problem but i thought ill report it anyways so when i create a popup like the one below and start blender trough vscode open the popup (important leave it open) and then reload the addon, click the ok button in the popup then blender crashes this behavior seems to pretty consistent.

import bpy

from cycles.ui import CYCLES_RENDER_PT_sampling, CYCLES_RENDER_PT_sampling_advanced
#from space_properties import PROPERTIES_PT_navigation_bar

class SM_Properties_Popup(bpy.types.Operator):
    bl_idname = 'sop.sm_properties_popup'
    bl_description = 'test'
    bl_label = 'Properties'

    bl_options = {'UNDO'}

    panels: dict = {}
    label: bool = True

    @classmethod
    def poll(cls, context): 
        return True #PROPERTIES_PT_navigation_bar.poll(context)

    def invoke(self, context, event):

        return context.window_manager.invoke_props_dialog(self, width=300)

    def execute(self, context):
        return {'FINISHED'}

    def draw(self, context):
        layout = self.layout

        #PROPERTIES_PT_navigation_bar.draw(self, context)

        CYCLES_RENDER_PT_sampling.draw(self, context)
        layout.label(text="Advanced")
        CYCLES_RENDER_PT_sampling_advanced.draw(self, context)

Thanks for the report. This issue is probably not very easy to solve. Also it is most likely a bug in Blender and not in the extension.
