I just completed installing 1903 from our WSUS.
One minor issue was upon completion and when the pc boots windows I received an error that it could not find/load System32\LogiLDA.dll which turns out to be related to Logitech Download assistant. I may have had a Logitech wireless keyboard and mouse at one time but not anymore. It must have been a remant because there were no Logitech references in Programs and Features. Quick fix was to copy the file from Windows.old\system32 into the current system32 folder. Error gone.
The big problem is in Windows Settings. I wanted to recheck app settings, default apps, etc. I can’t because when I try to open the Apps setting the Windows Settings window closes. So right now I cannot check default app settings the way I am supposed to.
I see 2 errors in application logs. The first is “Security Center failed to validate caller with error DC040780.”
The other error is “Faulting application name: SystemSettings.exe, version: 10.0.18362.1, time stamp: 0x066bf1a5

So be advised. I still haven’t even gone over everything but ran into this right away.
