Alright, so I had this issue as well. I had just reinstalled my Operating System (OS). So there was no installation of anything on the machine. When trying to run the "new" launcher for Windows 10, I was unable to "Sign Into Microsoft Store". So, as a backup, I followed the advice on Reddit, and Minecraft Forums, and installed the Windows 7/8 version using the .msi extension installer, not the .exe. Then I got this error listed in the bug report above.
Here's the resolution that I had found. I disabled all of the Windows 10 Firewall Settings, and then also installed Java 8 Runtime Environment. I am assuming that the disabling of the Windows 10 Firewall settings is not needed.
My thought is that this error occurs whenever there is no Java installed onto the computer. I'm assuming that the installer uses Java to download all of the required files, and since there was no Java installed, it couldn't grab those files. So the file game\launcher.dll isn't able to be downloaded.
To summarize, ENSURE THAT JAVA 8 RUNTIME ENVIRONMENT is INSTALLED. Java 8 at a minimum, but you can try with Java 16 if you wish as well.
