I fixed the permissions problems, but then I got this:

```
Is there a workaround?

Start with src/Library/Library.fsproj, src/Project.iOS/Project.iOS.fsproj, and src/Project.Browser/Project.Browser.fsproj, then reproduce the failure using the reported .NET SDK and dotnet build. Check the workload restore output and the SDK manifest permissions. Done means the affected projects build successfully on macOS without the reported resolver or missing-workload errors.
