Cannot load Redux ARM AU in Logic Pro

I am getting an error when loading Redux 1.3.0+ in Logic Pro on an M1 Mac. An error appears saying ’ An Audio Unit plug-in reported a problem which might cause the system to become unstable. Please quit and restart Logic Pro.’ and the plugin UI closes.

I can load the last Intel-only AU in Logic Pro fine (Logic running without Rosetta), and the ARM AU loads OK in every other host, eg. Reaper, Live.

I’ve tried deleting all the AU cache files and resetting all plugins in Logic. In the Logic plugin manager, Redux validates successfully.

Any idea what’s wrong or how to get more information? Thanks
