windows update failing with 0x80070661 for Windows Subsystem for Linux Update

Question

Today I received an update for Windows Subsystem for Linux Update, when trying to just run Windows Update, there was that update present, but it kept failing even after reboot with error code 0x80070661

When looking at event log, I found below error, but my computer isn't ARM64, instead it's x64

My solution to get rid of the failing update was instead to install another package I found at C:\Windows\SoftwareDistribution\Download\e689895d1281a65f028792f0df826b42\wsl_update_x64.cab, just unzip it on your desktop and run wsl_update_x64.msi
