You must have deleted the Cancel axis in your Input Manager. This is creating an error because you have something in your scene which requires the Cancel axis (most likely a Canvas and Event Manager). Here’s how to fix it:

  1. Go to Input Manager (Edit->Project Settings->Input)
  2. Increase the Size by one
  3. Set the Name to “Cancel” (without the quotes)
  4. Set the Positive Button to “escape” (no quotes) or something similar

That’s it! Now, you’ll likely find that you’ll have to do this several times for all the axes that are getting errors. If it’s easier, you can reset the Input Manager back to its default state by using the gear icon in the top right corner. Keep in mind this will delete any custom axes you’ve set up.
