Hi all, anyone having luck with the old macOS app store links on HT211683 

Stopped working for our teams this morning, which is a concern because we're still deploying Big Sur due to some Monterey incompatibilities on mandatory security apps.

You can obtain a signed package from Apple via link which Mr. Macintosh put together. You can also get them directly using SUS Inspector

There're a few posts about that, try softwareupdate command, change the version you want to download 11.4.0, 11.5.2, 11.6.1, etc

softwareupdate --fetch-full-installer --full-installer-version 11.6.1

or https://github.com/scriptingosx/DownloadFullInstaller 

Deploy it however you like
