Suddenly can't debug and up against a deadline

I'm running VS 2017 15.6.4. Today I am unable to debug my Xamarin Forms app. I can run the app but the debugger will not start. Looking at the logs I am seeing this error. Any help would be great.

Mono.Debugging.VisualStudio.DebugLauncher|Error|0|Controller.Launch ()
Xamarin.VisualStudio.IOS.MonoTouchFlavoredProject|Error|0|An error occurred while lauching Application for debugging
System.Runtime.InteropServices.COMException (0x89710015): Unable to start debugging.

The system cannot find the file specified.

    Found this answer on an other website which helped me:

    Some how Mono Debugging for Visual Studio was diabled ... Tools > Extensions and Updates> Mono Debugging for Visual Studio enable and restart VS solved it

    Yep ...Mono Debugging was disabled ... because like me (!) you foolishly believed Visual Studio when it said 'Mono Debugging is slowing you down - disable this extension to speed things up' and with the Visual Studio Satan whispering in our ears we proceeded to shoot ourselves in the foot

    I'm one of the fools! Suddenly everything is so slow, Visual Studio has become almost impossible to use since the last 2 updates. Mono Debugging took almost 10 minutes, it was slowing down for real!
