Hi! This issue isn't related to SendGrid but to (dependency) GuzzleHttp.

The URL you provide contains a double slash (//) which may cause an issue.

I suggest to attach the file locally (using absolute/relative path to the file) and verify it's existing using file_exists. Then it shouldn't be a problem to attach and send it using SendGrid.
If you don't have it locally, download it first by using (f.e.) file_get_contents.
