and the important bit is:

#include <GLFW/glfw3.h>
#include <imgui.h>

void framebuffer_size_callback(GLFWwindow* window, int width, int height) {
    glViewport(0, 0, width, height);
}

int main() {
    // Initialize GLFW
    if (!glfwInit()) return -1;

    // Create a windowed mode window and its OpenGL context
    GLFWwindow* window = glfwCreateWindow(800, 600, "CImGui Example", NULL, NULL);
    if (!window) {
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window);
    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);

    // Initialize ImGui
    igCreateContext(NULL);
    ImGuiIO* io = igGetIO();
    // Setup ImGui style, fonts, etc. here

    while (!glfwWindowShouldClose(window)) {
        // Start a new frame
        igNewFrame();

        // Render your UI here
        igBegin("Hello, CImGui!", NULL, 0);
        igText("This is a simple CImGui window.");
        igEnd();

        // Render ImGui
        igRender();

        // Clear the screen
        glClear(GL_COLOR_BUFFER_BIT);
        // Render ImGui draw data
        ImGui_ImplOpenGL3_RenderDrawData(igGetDrawData());

        // Swap buffers
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    // Cleanup
    igDestroyContext(NULL);
    glfwDestroyWindow(window);
    glfwTerminate();
    return 0;
}

it returns the error:
bool ImGui::Begin(const char*, bool*, ImGuiWindowFlags): Assertion `g.WithinFrameScope' failed.

I can't seem to get cimgui set up

and no matter what I do, it keeps giving me errors like this one

I'm on the edge of switching to something different
