Visual Studio 2017. New C# "Blank App (Android)" - or any app. Yesterday everything ran fine. Today the build succeeds, the deploy succeeds, but when I try to debug I get "Unable to start debugging. The system cannot find the file specified." The log file is attached. I have tried using my physical device, the built-in Nougat emulator, and the Visual Studio emulators. The message is the same. I tried rebooting.
