EC2 Windows Server instance unreachable (provisioned with EC2Launch)

I have been provisioning Windows instances on AWS EC2 using the Windows Server 1803 AMI image family on AWS. I have used the following AMI Ids:
- ami-08a02a307592e1af7
- ami-0246254cf1985c372
- ami-0f7768a8e6b521299
In addition I use EC2Launch (via user-data) to execute a set of powershell commands on the Windows instance. Depending on the contents of the user data sometimes the instance fails to get correctly provisioned. When that occurs the following problems are present:
- I am unable to get a Windows password from the instance. In the EC2 console a dialog pops up and tells me to wait at least 4 minutes.
- The system log in the EC2 console is empty and only shows a black background.
- I can still request a screenshot that shows my instance is up and running but I cannot login, since I cannot get a password.
I have so far started about 10 instances, each time the only difference was that I modified the user data. My problem is that since I cannot get access to the instance, I also do not know what change in the user data is causing a problem.
Of course I can debug that, by making one line changes at a time and start a new instance, but that is not only slow it also prevents me from learning about which kind of error occurred. I only know that a certain change line causes the failure, but I do not know not why?
Is there any way to recover from an error in a EC2Launch so that I still get access to the machine and can inspect the EC2Launch log?
Update
So far I have started about 20-30 instances. In about 50% of all instance starts the instance fails to successfully provision (I get no default password and cannot login), while in the other 50% the same instance configuration starts just fine.
