FRegexPattern constructor not found

Development Programming & Scripting C++

Hello,
i’m pretty new to c++ and ue so sorry if this is a stupid question…
i’m struggling a little to use the FRegexPattern and FRegexMatcher in my module. Seems like it’s not finding the constructors that take a FString as first parameter, only the copy and move constructors are found.

This is the HbRpg.Build.cs

using UnrealBuildTool;

public class HbRpg : ModuleRules
{
    public HbRpg(ReadOnlyTargetRules Target) : base(Target)
    {

        PrivateDependencyModuleNames.AddRange(new string[] { "Core" });

        PrivateDependencyModuleNames.AddRange(new string[] { "HbBase" });
    }

}

This is my RegexTest class:

#pragma once

#include "Core.h"
#include "Internationalization/Regex.h"

class RegexTest
{  
  public void Init()
  {
  FRegexPattern EscapeExpression(TEXT("^\\n")); <-- no instance of constructor matches the argument list   
  }
}
