I'm totally at a loss to what happened before you decided to reinstall Windows, format all data, used EaseUS to recover the file (just where did you recover that file to?). What events led up to this re-installation, formatting? Were you using BitLocker earlier? Were you using UEFI's or BIOS' HD password?
The solution set might include getting a powerful sector reader such as DMDE involved to literally scan each sector and hopefully pull out any words, phrases, sentences that can be sector-copied and eventually planted inside of a waiting text file.
Be forewarned, because apparently there are no backups of this word file, what we can suggest in a sentence or phrase in here will very likely translate into hours of intense study, time, effort on your part. Recovery, if possible, will only be harder, not easier.
