I've got a macOS app with a Widget Extension. When I try to run the scheme attached to this extension, WidgetKit Simulator "unexpectedly quits" and I get plenty of errors such as the ones below, that do not seem to be at all linked with the purpose nor the functionalities explicitly used by the app (nor the extension).
That's what I get in Xcode's console:
com.apple.siri.AssistantSettingsControls failed to find valid container bundle for file:///System/Library/ExtensionKit/Extensions/AssistantSettingsControlsExtension.appex/ at /System/Library/ExtensionKit/Extensions/AssistantSettingsControlsExtension.appex

com.apple.settings-intents.ScreenSaverIntents failed to find valid container bundle for file:///System/Library/ExtensionKit/Extensions/ScreenSaverIntentsExtension.appex/ at /System/Library/ExtensionKit/Extensions/ScreenSaverIntentsExtension.appex
In the error log (Console crash logs), the error description:
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x000000010428507c
Termination Reason: Namespace SIGNAL, Code 5 Trace/BPT trap: 5

I have observed that even if I try creating a new blank project and add a Widget Extension (keeping everything default) and try to run the scheme, I end up (after setting IDEPreferLogStreaming to YES in the environment variables) with the exact same errors.
What is the issue? How can I fix it?
