Windows 10: When I access any folder in file explorer, it causes file explorer to crash, taskbar...

Hi, I have a 5 year old hp laptop and whenever I try to access folders in file explorer, it crashes and causes shortcuts to not work, icons go black when I hover on them and my screensaver goes black, this only just started happening this week after a security update. I uninstalled the update but the problem persists.

One bad file can cause explorer to crash. Have you defragmented your HDD's lately?

 

File Explorer Crashes Due To Quick Access - Registry Fix?

I was following a guide suggesting putting custom items in the File Explorer Quick Access Panel.
I think I actually set something already in the quick panel - or a "divider line", which I was trying to move to the right so I could see what was in the quick panel already - to be in the quick panel.
At which point File Explorer crashed.
An attempt to open it, whether from a desktop folder or the taskbar, crashes (and also wipes and reups the taskbar contents).
Opening File Explorer Options from the start button, clearing the cache and unticking the two boxes for showing history in the Quick Access panel does NOT help.
Basically, I've lost file explorer. There must be registry entries that could reset the Quick Access to its original state.
Help!
Thanks)
