[HotChocolate] Sometimes throws InvalidOperatonException on AssertUninitialized in Types.Descriptors.Convention class

[Arsync]

Can't understand what's happened on server side while debugging. For the first time query works fine, but then can throw this randomly when queried again:

System.InvalidOperationException: Operation is not valid due to the current state of the object.
   at HotChocolate.Types.Descriptors.Convention`1.AssertUninitialized()
   at HotChocolate.Types.Descriptors.Convention`1.Initialize(IConventionContext context)
   at HotChocolate.Types.Descriptors.DescriptorContext.MergeExtensions(IConventionContext context, Convention convention, IList`1 extensions)
   at HotChocolate.Types.Descriptors.DescriptorContext.GetConventionOrDefault[T](Func`1 defaultConvention, String scope)
   at HotChocolate.Data.ProjectionDescriptorContextExtensions.GetProjectionConvention(IDescriptorContext context, String scope)
   at HotChocolate.Types.ProjectionObjectFieldDescriptorExtensions.CompileMiddleware(Type type, ObjectFieldDefinition definition, FieldMiddlewareDefinition placeholder, ITypeCompletionContext context, String scope)

In HotChocolate.Types.Descriptors, class Convention<TDefinition>:

private void AssertUninitialized()
{
    Debug.Assert(
        !IsInitialized,
        "The type must be uninitialized.");

    Debug.Assert(
        _definition is null,
        "The definition should not exist when the type has not been initialized.");

    if (IsInitialized || _definition is not null)
    {
        throw new InvalidOperationException();
    }
}
