No mention of SmartScreen on my side.
It was blocked before landing on my drive (using Chrome, not Edge) even before trying to execute and SmartScreen could kick in.
In addition, I have Edge uninstalled.

SM-S AND MD are in the same boat, anyway it's a false positive

or the website is compromised and the installer is tampered.
It is not the first time for MD to flag 7-Zip freshly released installer.
To keep on the safe side, I delete the installer and redownload it again a week later.
During such a period, if the website was compromised, it would be discovered and fixed.
If the problem the young age of the installer, it would not be considered young then anymore.

Indeed and even their own provider Cloudflare warns about them, but it does not block them, because it is technically safe, for now. Maybe it was hacked?!
That is a common behavior detection, usually false, I have seen it many times, especially when related to questionable apps like Nirsoft, ProcessHacker or games.
I am used to MD false detection of unsigned apps such as 7-Zip and Media player classic both the black edition and home cinema, and even PeaZip.7-Zip / Discussion / Open Discussion: 7-Zip 26.00
But I prefer to be cautious than sorry; I will not get dead if did not install the latest version the day it is released.
