Done executing task "CreateAppHost" -- FAILED.
A codesign change was added to the runtime recently:
This HostWriter.CodeSign method runs /usr/bin/codesign and sets RedirectStandardError to true, but does not set UseShellExecute to false.
Visual Studio for Mac runs on Mono. Mono throws an exception due to this check:
dotnet itself does not have a problem with the code as it is.

Regression?
I believe this worked in .NET 6 preview 6
Other information
Fix should be to set UseShellExecute to false in the CodeSignmethod.
