Can't install Cumulative Updates for v1909

I was having a different error than you, but still could not get any updates to work without failing after download - whether through Windows Update or downloading from the Catalog and doing it locally. After trying many people's lists of how to reset Windows Update, I finally did the Repair Install Windows 10 with an In-place Upgrade Installation & Upgrade by Shawn Brink. Other than going in and turning off Defender and the Firewall just in case to speed things up when it was "Getting Ready" (this step took about 2 hours for me), this worked flawlessly. I went from a busted 19041.264, to a repaired 19041.84. I was then able to go into Windows Update, and about five updates installed perfectly including the May and June cumulative updates. Just a suggestion if you run out of ideas, I had!
