Script blocker, quantum updates, command-line version.
I think the picture is wrong when it says about automated actions and scheduling that migrated from paid to free version.
Not quite as you described, but a few days ago my PC started, but hung for a maybe half a minute at the “Windows is starting” stage before the user accounts appeared. Then I noticed the ball in the tray was there but has a red cross (or was it a red line) part way across it. I thought maybe it hadn’t initiated a the boot stage.
Anyway I shut the system down, fearing it wasn’t protected, then restarted all all has been OK since. Wierd.
