Criterion had to issue a second printing of The Wiz due to audio issues.
The key for the second printing of the 4K was already added, but I haven't had any luck with the Blu-ray.
The public keydb.cfg contains an entry but I think it's for the first printing.
I submit the dump for this disk to svq@makemkv.com a week or so back. I thought to comment here as I was concerned due to it being a re-print it might be missed.
