Windows 10: Screen goes black when pressing lower brightness button

Hello!When I press the "lower brightness" button, my screen goes black, and it returns to normal when pressing the "higher brightness" button.For example, if my brightness is set to 100%, and I press the "lower brightness" button once, my screen goes black immediately; if I keep pressing it multiple times, though my screen is black, the brightness level will go down as normal. The screen turns on again with the corresponding brightness level once I press the "higher brightness" button again.Windows specs:acer Aspire A515-44

Screen goes black when pressing lower brightness button

Hello!

When I press the "lower brightness" button, my screen goes black, and it returns to normal when pressing the "higher brightness" button.

For example, if my brightness is set to 100%, and I press the "lower brightness" button once, my screen goes black immediately; if I keep pressing it multiple times, though my screen is black, the brightness level will go down as normal. The screen turns on again with the corresponding brightness level once I press the "higher brightness" button again.

Windows specs:
Edition Windows 11 Home

Version 21H2

OS build 22000.434

Experience Windows Feature Experience Pack 1000.22000.434.0

Any help would be really appreciated!

 

Black Screen after Log on

Laptop or Desktop (Very important) Windows 10 build 14.586 has a very annoying BUG: That causes Black Screen after login:
To date there is no cure until Microsoft send Update to fix the problem: OK here goes: When you Login and the Screen Goes Black ==>
Go to your Function Keys for Screen Brightness Chose to Lighten the Screen (This will make the screen Bright) so that you can view it.
The BUG is that they reversed (via Software) what the Brightness button does -- So it is currently reversed -- "Lighten" makes it Dark -- "Darken" makes it Bright ==> Go figure Microsoft screw the pooch on this one. . . .

This is for LAPTOP -- I have never seen this on Desktops but they are fixed rather than adjustable
