VST3 does not load and AU causes immediate serious program error and crashes Ableton Live

[az0863]

I am running the latest version of Ableton Live on Macbook Air M2 Sequoia 15.1 and I can't get Cardinal or Cardinal FX to work.

When i load the VST3 it says that the plug in cannot be loaded. When i load the AU Ableton immediately says "a serious program error has occurred. Live will shut down after this message box is closed"

I tried reinstalling and rebooting my computer. Still have same issues.

I don't seem to find anything online stating this issue, so I am wondering what's wrong.

Any leads?

Seconding this. I did a deep dive into the DistrhoPluginAU.cpp file and the AudioUnitRender function seems to consistently return a ParamError (-50) no matter what fixes I try to apply. Occurs during "Checking connection semantics" phase of auval.
