Function GetCurrentWindowRead

tutorials/common/imgui/imgui_internal.h:2700–2700

Windows We should always have a CurrentWindow in the stack (there is an implicit "Debug" window) If this ever crash because g.CurrentWindow is NULL it means that either - ImGui::NewFrame() has never been called, which is illegal. - You are calling ImGui functions after ImGui::EndFrame()/ImGui::Render() and before the next ImGui::NewFrame(), which is also illegal.

    // - ImGui::NewFrame() has never been called, which is illegal.
    // - You are calling ImGui functions after ImGui::EndFrame()/ImGui::Render() and before the next ImGui::NewFrame(), which is also illegal.
