He was probably privy to the way they were cheating, and his job involves watching video, so it stands to reason that he was doubtless among the 60 interviews MLB completed in their investigation.
In all their sleuthing—including reading over 76,000 emails—they found everything pointed to Cora and Beltran. Their names were highlighted, but not disciplined. And the reason was that the MLB policy on this stuff, going back to 2017, was that the buck stops with the manager and, ultimately, the general manager, so they were the ones suspended.
And, come on, I'm sure MLB would have rather pinned the whole thing on coaches than players, so if they had found anything worth mentioning on Hudgens he would have been named in the final report.
I say leave him alone.
