Debug Event on M1 Mac.

Steps to reproduce:
Open this build of After Effects on an M1 Mac 
Result: ...

Expected: No warnings, no events. I get the same message with Premiere Pro 15.4. After the warning and quitting the process AE opens just fine. I have not tested functionality beyond adding a couple of shape layers and animating scale and position.

Dynamic-link from Premiere Pro 15.3 and 15.4 also does not work. 
 
System info
    Application: After Effects (Beta) v18.4.0.30
    OS: macOS v11.4.0, RAM: 8.00 GB, CPUs (logical): 8

Dynamic Link works just fine between the current release of AE and PPro. It is just the beta versions that are broken. I suspect it has something to do with Premiere Pro Beta being a universal app (M1 compatible) and After Effects being an Intel (Rosetta) app.
