I made a brand new Visual Studio project and used your code to test. It crashes for the same reason..
-I am linking statically
-TGUI nightly build
-I built TGUI and raylib myself

..But afterwards I tested TGUI stable and I had no issues.
Sorry for wasting your time.

Exception thrown: read access violation.
this->_Vec._Mypair._Myval2._Myfirst was 0x111277529122129.

Minimal code with small menu:

Code Select Expand

auto menu = tgui::MenuBar::create();
  menu->addMenu("File");
  menu->addMenuItem("New Project");

 
  menu->connectMenuItem({"File", "New Project"}, [] {
    std::cout << "Let me print! \n";
  });
 

  gui->add(menu, "menu1");

It runs when menu item is not connected, otherwise there is a read access violation.

Okay, now I did add TGUI_STATIC define, but it appears I get a runtime access violation when connectMenuItem method of MenuBar is invoked.

Hello. I compiled TGUI as a static library with RAYLIB backend just fine. However, I get 3 unresolved symbols when I try to link it with my application. I am on a Windows environment.

Output:
