I am trying to debug a test app using Hot Restart but it will not launch. The Build Output window shows that the app has been successfully deployed to the iPhone. I see the icon on the iPhone but when I try to start the app it opens something for a short period of time and then it closes. The Build Output window reports that: An error occurred while trying to launch the app 'MVVMDemo.iOS'. Details: Error running hotrestart: 'An error occurred while disposing the 'com.apple.debugserver' service. Details: Value cannot be null.'. Command: 'launch -u=8c5ef99b1c1907ce22b4eb3f5d4a848839e78255 -i=com.companyname.MVVMDemo -p=10000 -d="C:\Users\xxxxx\AppData\Local\Xamarin\iOS\DeveloperDiskImages\14.3\DeveloperDiskImage.dmg" -w=True'
