It’s an issue when a plugin ends up attaching a native thread to the runtime, which then does blocking calls to the OS. Several Unity plugins like Parse, FMOD, UMP (Universal Media Player), ZFBrowser, or Embedded Browser are using native threads. In case you are still experiencing the problem, run a Developer Command Prompt for Visual Studio as Administrator and use the following command: devenv /setup Try removing the following folder to reset the MEF cache (close Visual Studio before doing this): %localappdata%\Microsoft\VisualStudio\\ComponentModelCache This issue can be due to the Visual Studio MEF cache being corrupted. Do not rename the main Unity executable, as VSTU is only monitoring "Unity.exe" processes.You can try to temporarily stop any extra software to see if it changes something. Some programs, like Team Viewer, can interfere with process detection.Try to temporarily disable your firewall or create rules for allowing TCP/UDP networking between VS and Unity.
