I am building an ASP.NET Core 8.0 application for arm64 via a github action. Upon the dotnet restore command, the error in the title is thrown and the build process is aborted. I am building the asp.net template project, there is no additional nuget packages or even additional code. When building the application locally to x64, it works fine.

Here are some relevant files:

I have no idea what the message task is and I don’t really find anything about that.
