Same issue as everyone. I have three different OWC docks to play around with and have seen different things. It was stable for awhile but kept ejecting external drives. After installing 12.4, it's totally game over. It won't keep any dock active for more than a second before ejecting. I've already been through OWC support, I've installed the software they've asked to install and followed their steps. I currently have no ethernet which is mandatory for my job and the computer is useless for me without external harddrives.
