This issue can easily reproduced with this Azure Maui Sample

https://github.com/Azure-Samples/ms-identity-dotnetcore-maui

Tried workarounds

Added explicit app package reference from nuget https://www.nuget.org/packages/Microsoft.WindowsAppSDK/1.6.240923002

with this its builds fine but then embedded browser never opens.

Same problem here! I'm using an older version 4.61.3, but it is the same with the latest build as well 4.66.1

In my case the problem started after updating Visual Studio to it's last version 17.11.5.
