I know it is this extension because before everything locks up, I have some time to open the Extensions app and disable it. I have been through my extensions one by one and confirmed it is Blur My Shell that causes the issue. When I say locked up, I mean that everything becomes non-interactive, no keyboard or mouse input works and the startup sound stutters and loops. It is worth mentioning that enabling it some time after startup, the extension works perfectly and causes no issues with the system. I'm happy to provide any other feedback.
