The template ".NET MAUI App" was created successfully.

dotnet nuget list sourceto check the source of nuget. You can paste the result here.Then, can you access nuget.org in this computer? You will get json data in this page/. If you do not have nuget.org and can access nuget.org, you can add it
dotnet nuget add source https://api.nuget.org/v3/index.json -n nuget.orgIn the end, you can try to restore again.
dotnet restore
