Redstone 3 (16170) Breaks UWP Debugging in VS 2017

Since the computer updated itself to the first Redstone 3 release from the final Creators Update it seems to have broken UWP app debugging in VS 2017 (PC is set to Insiders Fast). In the properties for an app I can only target the Creators Update and not the current release so I’m wondering if this is why.

I realise I can roll back my build but would rather fix this if anyone is aware of a workaround.

The error is:

Exception thrown: ‘System.IO.FileLoadException’ in System.Private.CoreLib.ni.dll

This also happens with the Xamarin Challenge which I completed and which was working.

Does anyone know how to fix this and are others on the fast ring experiencing the same issue?

Thanks

Robin
