Automatically loading layers on startup (problem) using PyQGIS

Question

I made a small code to fetch some PostGIS layers into QGIS and apply them with qml style, like the following:

import os
from qgis.core import QgsVectorLayer, QgsDataSourceUri, QgsVectorLayer, QgsProject

uri = QgsDataSourceUri()
uri.setConnection(#CONN_INFO)

city_filter = 'Cairu'

uri.setDataSource("public", "dende_mp", "geom", f"nom_munici = '{city_filter}'")

vlayer = QgsVectorLayer(uri.uri(False), f"car_{city_filter}", "postgres")

QgsProject.instance().addMapLayer(vlayer)
vlayer.loadNamedStyle('C:\\Users\\curyp\\OneDrive\\Desktop\\Projetos\\project_1\\styles\\tam_area_car.qml')

uri.setDataSource("public", "sigef_visita", "geom", f"municip = '{city_filter}'")

vlayer_sigef =  QgsVectorLayer(uri.uri(False), f"sigef_{city_filter}", "postgres")
QgsProject.instance().addMapLayer(vlayer_sigef)
vlayer_sigef.loadNamedStyle('C:\\Users\\curyp\\OneDrive\\Desktop\\Projetos\\project_1\\styles\\tam_area_sigef.qml')

It's working fine, but for some reason after I close and reopen QGIS, these same layers get loaded again, with styling and all. It also asks me if I want to save or discard project modifications. I've tried to delete layers, discard editings, calling QgsProject.instance().removeAllMaplayers(), but none of these works.

Any ideas?

After some time away from qgis scripts, this is the solution I found:

Apparently, when you try to add a python script file to QGIS "add scripts to toolbox", it gets coppied to qgis scripts folder and executed on startup.

In windows, go to: C:\Users\User\AppData\Roaming\QGIS\QGIS3\profiles\default\processing\scripts and remove your personal scripts that are wrongly being executed on startup.

Version of QGIS tested: 3.22.14
