My company's NuGet feed is inaccessible via the package manager interface in Visual Studio 2022.
My company has a NuGet source with an URL like https://elcia.pkgs.visualstudio.com/_packaging/MYCOMPANY/nuget/v3/index.json. Authentication is linked to our active directory and should all just work, and has worked in the past. I can access the URL in my browser, and I can access the feed via the package manager console inside Visual Studio. nuget list -Source MYCOMPANY works just fine. But the package manager interface can't access the feed, and leaves a 401 unauthorized error in the output.
Restarting VS, restarting my machine, deleting my credentials in the credential manager have no impact.
It's somehow linked to updating my Visual Studio licence. When I choose Help => Register => Check for an updated licence it all works.
