Now, back to me: I have the same problem as the OP. I am in Belgium with a Belgian IP address, and am trying to download the Windows 10 multi-region version in English (United States). I am using an Apple Macbook Air.
I wouldn't recommend a Dev build at this time due to a current bug
There's a direct link to the Beta build at the end of this thread.

FYI
Even though Windows 11 ARM Insider Preview works on an M1 via Parallels or similar, the scenario is not officially supported by Microsoft.
Options for using Windows 11 with Mac® computers with Apple® M1® and M2™ chips
Parallels® Desktop version 18 is an authorized solution for running Arm® versions of Windows 11 Pro and Windows 11 Enterprise in a virtual environment on its platform on Apple M1 and M2 computers.
btw: your profile doesn't show you as Insider, you need to register before you can download VHDXs
