[Bug]: Error changing aws_codebuild_fleet resource after importing

Terraform Core Version

1.9.5

AWS Provider Version

5.67.0

Affected Resource(s)

aws_codebuild_fleet

Expected Behavior

When trying to modify the configuration of this resource, the changes should be applied without any issues.

Actual Behavior

If the resource has been imported, the modify fails when trying to perform the UpdateFleet operation, stating the ARN of the resource is invalid.

Relevant Error/Panic Output Snippet

aws_codebuild_fleet.this: Modifying... [id=MyFleet]

Terraform Configuration Files

aws_codebuild_fleet.zip

Steps to Reproduce

Create manually a compute fleet named ToBeDeleted1 using the AWS console. Set Overflow behavior to Queue.
Import resource: terraform import aws_codebuild_fleet.this ToBeDeleted1.
Run terraform apply -auto-approve.

Debug Output

Panic Output

Important Factoids

Comparing the resource objects in the Terraform state file between an imported resource and a resource created with Terraform, the only difference is in instances.attributes.id: the first one contains the name of the fleet, while the second one contains its ARN.

The error says that the ARN of the fleet is invalid, which makes me think that the ARN is being read from id, which in one case it contains the ARN, but in the other one, it contains the name.
