Error in Visual Studio if Path contains directory you do not have permission to view

NuGet Product Used

Visual Studio Package Management UI

Product Version

Visual Studio Version 17.13.0

Worked before?

Version 17.12 (I think) - Probably prior to NuGet/NuGet.Client#6177

Impact

It bothers me, a fix would be nice.

Repro Steps & Context

Since upgrading Visual Studio, every time we open a project, the following error appears:

The path in question is for some tooling our IT team has installed - it adds itself to the machine wide path, but users don't have permissions on the file system to access the directory.

I believe this regression was introduced by NuGet/NuGet.Client#6177, specifically with https://github.com/NuGet/NuGet.Client/blob/555651e288f0276f2808dde7a40276a84b9adf3e/src/NuGet.Core/NuGet.Protocol/Plugins/PluginDiscoverer.cs#L243-L263 - it is possible for a user to have permission to see that a directory exists, but then not have permissions to view it - the loop likely needs some kind of continue on access denied logic.

Repro Steps

1. Create a directory which you can see, but do not have permission to access
2. Add this to the path
3. Open Visual Studio

For reference, below are the permissions for the directory in question

How can I disable this disk scanning? I absolutely don’t need it, and it only slows down the already slow Visual Studio. Thank you.
