I can't install 18946. I copied ISO to usb with latest Rufus (choosed GPT) and when I make a boot and choose "UEFI: Sandisk", it move to BIOS. It's look like my laptop only support Windows 10 64bit.
You could have uploaded the UUP files like Enthousiast did, then you wouldn't be breaking the rules. That looks ugly, black font with dark theme enabled and the user picture at top should be a bit lower. I know this is very far from finished.
There is a difference between x64 and x86. The one you link to, the UUPs, is just x86. The other is x64 which I downloaded, set to install default Insider Start Menu, and converted to Enterprise, and ProWorkstation. I also made an AIO size 3.33 GB. Easy enough, but life is good so why not test new builds? The last I remember you can't test a build with only a screenshot!
