Unhanlded exception if CWD is deleted

### Describe the bug
When the current working directory is deleted (say in another tab), the dotnet commands stop working.

### To Reproduce
0. Open 2 command prompts
1. In prompt 1, cd into a new directory - `~/DotNetTest`
2. In prompt 2, delete that directory
3. In prompt 1, execute `dotnet nuget locals http-cache -c`
