InvalidOperationException: Multiple constructors accepting all given argument types have been found in type

I suddenly have the following error message after created my fourth controller in ASP.NET Core 2.2:

An unhandled exception occurred while processing the request.
InvalidOperationException: Multiple constructors accepting all given argument types have been found in type 'noblesbank.Controllers.AccountController'. There should only be one applicable constructor.
Microsoft.Extensions.DependencyInjection.ActivatorUtilities.TryFindMatchingConstructor(Type instanceType, Type[] argumentTypes, ref ConstructorInfo matchingConstructor, ref Nullable<int>[] parameterMap)
