Thanks for filing this issue @auberta2!

This appears to be another case of a missing Current state

[auberta2]

The stack trace looks much similar you're right. Any known workaround waiting for a fix ?

[auberta2]

Upon investigation of the logs, I could workaround the bug by running :
terraform state rm aws_instance.backend-win

where backend-win was a collection of EC2 instances with a variable based count property
