Solved Answer

Recently, some people reported experiencing a Blue Screen error^[1] in Windows. The reported Stop Code is SYSTEM_THREAD_EXCEPTION_NOT_HANDLED, and the culprit is shown as Amdacpbus.sys. It is a system file that is associated with AMD hardware and software on a computer running Microsoft Windows.

Amdacpbus.sys is a driver^[2] file that is responsible for communicating between the operating system and certain AMD hardware components, such as the AMD audio controller and AMD graphics card.
