GoogleCast framework crash on iOS 14

Question

I'm trying to use google cast sdk in my project, for some reason it crashes without giving a proper error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]' terminating with uncaught exception of type NSException

I see one possible change done in that time was related to the Podspec which included the cast SDK. Some of those lines were not there before and it caused the Google Cast Resources to be missing in the bundle and crash (below is the partial podspec):

Pod::Spec.new do |s|
  s.dependency 'google-cast-sdk-no-bluetooth', '= 4.5.0'
  s.xcconfig =  {
      'CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES' => 'YES',
      'OTHER_LDFLAGS' => '-objc -ObjC -lc++ -framework "GoogleCast"',
      'GCC_SYMBOLS_PRIVATE_EXTERN' => 'YES'
  }
