Lock Screen glitching occasionally

My lock screen has been glitching a few times in the past month.
Sometimes when i press a key to go to the login screen, the screen goes black and resturns back to the lock screen after a few seconds. After trying again a few times, I force restarted it and it started working normally.

Today the same thing happened again, but with a strange window in the lock-screen. I have attached an image of it.
Can someone please help out? Thanks in advance!

I am using Windows 10 Home x64 version 1909 on my second computer. (The laptop)
