I believe this might have to do with the "user-mode" version of Pace. In essence, an Apple macOS restriction to prevent drivers from running at a lower level in the system as a security feature. Current iLok software could determine which mode it runs at once installed. So install on Big Sur, iLok runs at kernel-mode. Install on Monterey, kernel-mode fails so it runs as user-mode.

And if a plugin wasn't compiled with the user-mode ability (whenever that was released as part of the PACE Eden toolkit), it fails authourization on user-mode systems.

[This is all conjecture but seems to fit with what is observed. And I know Monterey restricts drivers]
