That update was released on the 8th December and at present only has 2 known issues, none of which describes the current problem.
That problem is that when these users run chkdsk c: /f (ie checkdisk with immediate repair) their PC hits a Stop-Error NTFS File System blue screen and becomes unbootable.
A ChkDsk performed in the pre-boot environment finds a number of errors in the Master File Table, which is fortunately fixable, again, via chkdsk c: /f .
It is not known how widespread the error is yet, but numerous users have confirmed being affected.
Given the reports, it may be wise to delay installing KB4592438 or install it for a few weeks until the situation is resolved one way or the other.
