System.Exception: Restore operation failed.

When running `dotnet format style -v diag` i get an exception as follows:

```
The dotnet runtime version is '6.0.3'.

`dotnet format --version` results with `6.0.252703+68bc36719088c86b0ff01334039b0611741b8276`

Also, this issue does not appear when running under CI with the same repo.

Any guidance on how I might be able to investigate further?
