Thank you!
I used the current media creation tool to update to the latest version 20H2. I verified that the hardened configuration settings have stayed the same.
For others,
I installed the media creation tool (MCT) on an external drive. I logged in normally and did not boot into the MCT. I opened the drive and executed the "Setup.exe". Then I checked the box to keep my files and applications. Let the program run for over an hour and success!
