Terraform Core Version

1.2.0

AWS Provider Version

5.10.0

Affected Resource(s)

aws_launch_configuration, asg

Expected Behavior

Launch configuration should be created so we can create ASG

Actual Behavior

Resource fails to create, "empty result" error message despite using the same code in several other environments within the same region.

Relevant Error/Panic Output Snippet

`│ Error: creating Auto Scaling Launch Configuration (REDACTEDRESOURCENAMEXXXXXXXXXXXXXX): empty result

Important Factoids

We have several other environments that match the exact configuration of this environment (GEO location etc), so not sure why this would fail unless provider requirements have changed but the Error doesn't give too much away to advise of that.
