Avast stopped working, uninstalled, tried to reinstall but failed

I came home to an Avast message that it nees to restart. I did. Avast no longer worked. I could not open the UI, it displayed a message that said Loading, this won’t take long but never loads.

It would not uninstall. Instead is says that setup is already running. An Avast tech attempted a repair. That failed. Finally, I uninstalled using Avast Clear.

Attempts to reinstall failed.

Here is the log:
