I've been trying to install Windows Update 2004 for x64 Systems KB4596242, but I keep getting the following error message every single time.

Thinking that it was a corrupt download, I cleaned out Windows/Software Distribution to force Update to redownload which has worked before but the same result happened again. Oddly enough, looking at Task Manager shows that Windows Modules Installer Worker
continues to run even after this update "fails."
ReportingEvents.log reads as thus

I have tried to download the update from Windows Update Catalog and manually install but the update for some reason fails there as well, finishing with an error message stating that the update was not installed.
