Photoshop: Grey Point Tool error "Could not use the gray point tool because the settings in the file are invalid" is any channel's curve is inverted

Getting this " Could not use the gray point tool because the settings in the file are invalid" error very often when color correcting scanned negatives with Curves like in this post:

Every photoshop version from ps 6 to 21.1.3 displays the error.
Unable to replicate on ps 5.5 or older.

Appears to have been fixed in photoshop 2021 (ps version 22.0)

Thank you
