Could you double check that the chromedriver has been updated? I see in your logs that it is still referencing v2.10. I just tested it out by downloading v2.10 and I get the same error. Updating chromedriver to v2.14, the error does not occur.
If you open up command prompt and type the below line, you can find out the current version you have. “D:\softies\Programs\Appium\node_modules\appium\build\chromedriver\windows\chromedriver.exe -v”
This is your log indicating chromedriver version.
info: [debug] Spawning chromedriver with: D:\softies\Programs\Appium\node_modules\appium\build\chromedriver\windows\chromedriver.exe
