If you only need files from the machine, you could try exporting it as an AMI into EC2. Instead of launching it as a running server and risking the kinds of conflicts you're describing, you could simply create EBS volumes from the snapshots in the AMI and attach the resulting EBS volumes as secondary volumes to any regular EC2 instance. Mounting the file systems/drive letters would give you access to the file contents.
Finally have the solution. I was really close last time, but unfortunately, I had chosen 'Windows Server Core Basic' instead of 'Windows Server Basic'. 'Core Basic' has no GUI, nothing. 'Basic' has the essentials, including the Explorer shell and access to the clipboard. Once I created the correct instance type (didn't choose 1gb RAM 'free tier', chose t3 (cpu type) and g3 (SSD type) and since this instance is only temporary to restore data from the snapshot volume, who cares about slight cost), I was easily able to extract the SQL database from the attached volume, then detach the volume and then delete the instance.
Also, since I may need to restore data from snapshots in the future, I created an 'instance template' consisting of all the steps needed to create another instance. Next time I need to restore data from a snapshot, all I'll need to do is 'create instance from template' and in a couple of clicks, the instance will be ready to use. Of course, I'll need export the image from Lightsail to EC2, then create and EBS volume, then attach the volume to the instance.
This is far safer than risking a production Lightsail instance running Windows 2019 because of the potential SID conflict. Still not sure if using Lightsail to 'create instance from Snapshot' is safe, even if the original instance is stopped while the 'copy' instance is running. It's possible that software licenses could become invalidated.
OK, I finally found the correct reference: https://docs.aws.amazon.com/lightsail/latest/userguide/amazon-lightsail-creating-ebs-volumes-from-exported-snapshots.html and now there's a volume. Now, I guess I need to create a Windows EC2 instance and attach the volume/mount. Is it possible to attach this volume to a new Lightsail instance as a secondary volume (I'm guessing it will be much easier than creating an Windows EC2 instance)?
Now that I have a volume created, there's no option anywhere to simply create an EC2 instance, then attach that volume. Also, there's no option to not encrypt the volume. My guess is because it's forced to be encrypted, when I try to 'attach volume', the LIghtsail instance is not available in the list of available instances. I guess this is done deliberately by Amazon to keep the process as artificially complex as possible (?!)
The only option is to create an instance from the AMI that was imported. This defeats the purpose - it's the same thing as the Lightsail option to 'create instance from snapshot', which is what I originally posted about.
I have to 'launch instance' to be able to actually create a new instance (?!) Now I have a Window instance with the EBS volume attached. When I launch this instance, it's completely crippled, no UI, no explorer shell, even the CD command is completely crippled (command line switches disabled). Used DiskPart to put the volume online as D:, but with no explorer shell and no way to utilize the clipboard, how will I transfer files out of the RDP session?
Hi,
It was unfortunate you received the earlier suggestion to move to EC2. Please instead try recovery within Lightsail itself by creating a snapshot of the instance's root disk and then using a disk created from that snapshot as an attached disk on a new instance for data recovery. Please find steps in https://docs.aws.amazon.com/lightsail/latest/userguide/amazon-lightsail-create-an-instance-root-volume-snapshot.html . For the step 1 and 2 from that guide, you can instead use AWS CloudShell from the browser itself in place of AWS CLI. Please find CloudShell usage details in https://docs.aws.amazon.com/lightsail/latest/userguide/amazon-lightsail-cloudshell.html#lightsail-cloudshell-launch-and-use
Thanks
I can't create a new snapshot of the root disk. I need to access data from an earlier snapshot, since the current instance is missing this essential data.

There is no need to export to EC2 here. Lightsail itself supports creating a volume snapshot of the root disk of an instance and using a volume launched from that snapshot as the secondary or attached disk to a new instance for data recovery. . https://docs.aws.amazon.com/lightsail/latest/userguide/amazon-lightsail-create-an-instance-root-volume-snapshot.html
