Media Creation Tool Error 0x80042405 0xA001B

I must be doing something wrong because I always have the update fail with some BS error like this. What are the proper steps to run this tool?

I download the tool to the desktop. I'm on an Admin account. I insert a 16GB thumb drive. I format it. I start the tool. I point it to the thumb drive. During the phase where the files are copied to the USB, I get some stupid error like this:

Why are my steps not good enough? Where is the hole in my logic? Or is this tool just written poorly. I'd like to use stronger language here as I used to have to start it all over again and burn bandwidth trying this failed endeavor over and over.

I've heard people make it work by running the tool FROM the USB. Why would that matter? I've tried to write files to the thumb drive just after the format and before running the tool to make sure I have successful writes. Doesn't help. 

As a workaround today, I left the error up for a bit. Tried to access the thumb drive and it said it needed to be formatted AGAIN! So I did. Then I just opened the C:$Windows.~WS\Sources\Windows and copied the files to the drive by hand. Made the dang thing myself! WHO WRITES THIS STUFF??

    That is sad to hear & worse than this thread is about. I think you belong in this one instead...

    https://answers.microsoft.com/en-us/windows/forum/windows_10-update/cannot-install-update-1903/ad949b1b-982c-40f6-a535-cfab5a8f071d?messageId=053224a6-41d1-48b1-864b-f390024035a4&page=1

    Cannot Install Update 1903

    And I think lacrumb is onto something. You should have tested & secured the original install of 1903 before trying to install Xbox Game Pass (BETA). As is said in here...

    https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install/clean-install-windows-10/1c426bdf-79b1-4d42-be93-17378d93e587?messageId=da8cd190-dfa8-4e39-8417-b1802a269196

    Clean Install Windows 10

    "

    Reinstall programs

    Install programs slowly over time to gauge performance changes after each. You can roll back bad effects of a Program install or Update(s) by uninstalling it or using System Restore.  Often these will not repeat but if so check you have the latest Net Framework from Microsoft or report it back here. 

    "

    So - after you do the clean install & it seems to be running well, secure it by making a Windows system image backup or equivalent (with a 3rd-party tool). Then, do big installs slowly always ready to reverse one with System Restore. But if that fails, then restore the image.

    Before you tried to install the Xbox Game Pass did you try to do any thing else?

    Something is definitely broken with this upgrade...

    I tried upgrading it from Windows Update, and the update failed. The PC tried to restart but only shutdown. Then when I turned it on Windows Update said 1903 was installed yet I couldn't install Xbox Game Pass (BETA) app. 

    Then I tried doing a fresh start. No success. Same thing, windows didn't even delete everything, or if it did, it undid changes on next boot.

    Then I finally asked Windows Support for a hand, then they suggested Windows Creation Tool. Same thing happened, but worst. On my next boot I got a prompt from a desktop.ini file created somewhere with this inside: 

    [.ShellClassInfo]

    LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787

    There was another window opened but it was closed after I tried it again.

    Now I will have to erase everything from my PC to install a freaking upgrade so I can use Xbox Game Pass for PC... This is really annoying. 

    Didn't you detect anything wrong on it, Microsoft, for real? I mean, seriously... This is the first time a official update is giving so much headache for so much people...
