Every Other test fails to launch App when running multiple tests one after the other

When selecting multiple scenarios to run every other test fails to launch the app with the error message:

System.InvalidOperationException : An unknown server-side error occurred while processing the command. Original error: Error occured while starting App. Original error: Activity used to start app doesn’t exist or cannot be launched! Make sure it exists and is a launchable activity.

If i select 5 of my tests to run which should run one after the other, the first, third and fifth test pass and the second and fourth fail.

It doesn’t matter if I start the appium server from the code or locally from the command prompt.
Android 6.0

My capabilities are set as follows:
commandTimeout = 120
fullReset = true
platformName = Android
plaftormVersion = 6.0.0
deviceName = Cubot
udid = "X562XXDH68220238
app = path to apk
appWaitActivity = md5ca5626392feb4628a1f95c95504ee963.*

I know these settings are correct as they work for three of the tests and if I ran all my scenarios selecting one at a time they all pass.

Any ideas how to fix?

I’ve attached the appium log from running 5 scenarios
