Hello, I'm in a big project app with unit testing and ui testing running well. Recently, one member of team, buy a MacBook Pro M1 with Big Sur 11.1 and try to execute the ui testing with the new Xcode 12.4 (available today 27/01/21 from Mac AppStore). When he selects any simulator with iOS 13.7 it's ok, but if he selects iOS 14.4 then fail. It doesn't matter if it's an iPad or an iPhone. The error talks about architectures but the settings haven't any custom config depends iOS version. Showing All Messages MYAPPUITests-Runner.app (72942) encountered an error (Failed to load the test bundle.

Can you think something ? Regards.
