Error: The terraform-provider-aws_v4.41.0_x5 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

@benjamint-bsquare I have opened a PR that will resolve the crash you are experiencing. Basically, the crash is happening after the disk fails to attach and when its attempting to display the error returned by AWS.

This PR will not resolve your current config however. I added a test with your exact path and this is what is returned by the AWS API:

  Error: AttachDisk Amazon Lightsail Disk Attachment (tf-acc-test-454657590263985767): InvalidInputException: The disk path is invalid. You must specify a valid disk path.
        {
          RespMetadata: {
            StatusCode: 400,
            RequestID: "571bffcb-ea15-46cb-9718-7a141552c1d4"
          },
          Code_: "InvalidParams",
          Message_: "The disk path is invalid. You must specify a valid disk path."
        }
        ```
        
You will need to update your path to be a valid disk path. (e.g., /dev/xvdf).
