Windows 10: Blank dark turquoise green sign out screen

My tool bar froze -totally unresponsive. So I clicked on the main screen and clicked on sign out. A dark turquoise green screen appeared with a message signing out with circle going round. After ten minutes of this I tried turning the laptop off. Signing out message disappeared leaving the blank screen same colour. Left it on all night but no change. Any advice on how I overcome this and restore Windows screen? Not sure if it is Windows 10 or 11. Laptop 5 years old.

Re-started Windows Explorer: My screen went blank/dark blue

1. My taskbar disappeared first. I opened task manager and found Windows Explorer at the bottom of the processes.

2. I pressed re-start and normally, the screen goes back to normal. I didn't do the steps you list in 2.

3. No. I just get the list.

4. I restarted my computer and nothing changes. I turned it off and waited, then turned it back on. I get the sign on screen. Enter my password and then the dark blue screen appears.

That 's it.
