This should not happen unless you install assets or open the project for the first time.
Check the editor.log for details. Perhaps this helps pinpoint the issue. Specifically, what package it tries to install. Perhaps this may be a (defunct) editor script trying to install an already-installed package all over again, every time.
I will check the logs because this is happening to the whole team not only me. Also in different projects as well.
So there should be a specific package messing things up
