Unable to run WidgetKit widget on device or Simulator! - Please Help

Hi Devs! I am trying to build a widget for my app MathFlash Fun, but I am unable to deploy the widget to my iPad and the Simulator!



The lldb says dyld: symbol '_$s9WidgetKit22IntentTimelineProviderP11placeholder4with5EntryQzAA0dE7ContextV_tFTq' not found, expected in '/System/Library/Frameworks/WidgetKit.framework/WidgetKit', needed by '/private/var/containers/Bundle/Application/3CA7A491-1A1F-4975-A010-39F6964A9A9A/Math Flash.app/PlugIns/CanYouWorkNowWodgetExtension.appex/CanYouWorkNowWodgetExtension'
(I accidentally named the widget Wodget!)




Xcode also shows me a SIGABRT and shows a pop-up which says SendProcessControlEvent:toPid: encountered an error: Error Domain=com.apple.dt.deviceprocesscontrolservice Code=8 "Failed to show Widget 'com.duckida.CanYouWorkNow.CanYouWorkNowWodget' error: Error Domain=SBAvocadoDebuggingControllerErrorDomain Code=1 "Failed to get descriptors for extensionBundleID (com.duckida.CanYouWorkNow.CanYouWorkNowWodget)" UserInfo={NSLocalizedDescription=Failed to get descriptors for extensionBundleID (com.duckida.CanYouWorkNow.CanYouWorkNowWodget)}."

My Mac is a 2019 MacBook Air with macOS 10.15.4
