Black screen crash in IOS

Just recompiled with current version 3624 and App launches with black screen in IOS sim with error:
assertion failed: 19H2 18A8394: libxpc.dylib + 51172 [5B766255-3DAE-3096-A090-3974BE256194]: 0x7d

Any help would be appreciated.

Have you tried a real device? Unfortunately, many of the libraries now don’t have the x386 and x86_64 slice. Without these slices, they will not run in the sim. They are not needed for production and once the entire echo system is silicon (arm) they won’t even be needed for sim.

found the issue. OneSignal.EnableInAppAlertNotification(true) is causing the issue. it is apparently not supported anymore and true is the default anyway.
