3] Troubleshoot in Clean Boot State
Sometimes, an app tries to write into the proxy settings but fails because of adequate permission. Since it is difficult to figure out a particular app, the best way is to use the Clean Boot PC method to ensure it’s the third-party app causing the problem. Second, you need to figure out which app is behind the screen.
Check the list of available apps in the Task Manager’s Startup section. Since you are receiving this error as soon as you login, it has to be one of the apps that will be a problem.
Disable the suspected app from the startup, and check if you receive the same error next time you log in to the PC. If you don’t, then that’s your app. Now, you can either uninstall the app or reinstall the app with the required permission to ensure it can write into proxy settings.
