Operating System: the system itself (like corrupt installation of OS or some components like .NET Framework) or user profile.  Some security software may make it necessary to disable InfoCenter:
Solution:

Press 'WINDOWS-R' on the keyboard to bring up the Run window, enter REGEDIT and click 'OK'.
Navigate to and select the following folder:

"HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\Rxx.x\ACAD-xxxx:40x\InfoCenter"

This path is unique for each version of AutoCAD. You can see what 'ACAD-xxxx' refers to by selecting the path and then looking at the keys on the right pane of the Registry Editor. One of the keys will show the install path to the associated version of AutoCAD. The '40x' number signifies the language version of AutoCAD.

On the right pane of the window, double-click 'InfoCenterOn'.

Enter a value of 0 (zero) and click 'OK'.

Note: If multiple versions of AutoCAD are installed, the InfoCenter needs to be disabled for each one.

Turn OFF the Text Cursor setting in Windows 10 and 11:
Navigate to 'Windows Settings' then 'Ease of Access' then 'Text cursor'.
Turn 'OFF' the text cursor.
Update the video driver on your system to the latest version from your graphics card manufacturer and run the installer for DirectX to make sure it is up-to-date.
