For unknown reason openGL GLSL shader programm cant link correctly, log is empty. Shaders compiled correctly.

Trying to do:
CompileShaders("Data/Shaders/ui", 0b01, MainUiShader);
gives an error: “ERROR: Cant link shaders”.

Here is header with functions:

void CompileShader(std::string ShaderFile, GLenum ShaderType, GLuint ShaderVariable) {
    LoadFile(ShaderFile);
    ShaderVariable = glCreateShader(ShaderType);
    const char* ShaderSource = TempData0.c_str();
    glShaderSource(ShaderVariable, 1, &ShaderSource, NULL);
    glCompileShader(ShaderVariable);

    glGetShaderiv(ShaderVariable, GL_COMPILE_STATUS, &TempValue);
    if (!TempValue)
    {glGetShaderInfoLog(ShaderVariable, 4096, NULL, Log);
            std::cout << "ERROR: shader compilation failn";
            std::cout << Log << std::endl;}
    else {std::cout << "Shader compiledn";}}

void CompileShaders(std::string ShaderFile, int8_t ShaderTypes, GLuint ShaderVariable) 
{
    ShaderVariable = glCreateProgram();
    if ((0b01 & ShaderTypes) > 0) {
        CompileShader(ShaderFile.append(".vsh"), GL_VERTEX_SHADER, Stemp[0]);
        glAttachShader(ShaderVariable, Stemp[0]);
        std::cout << ShaderFile;
        ShaderFile = ShaderFile.substr(0, ShaderFile.size() - 4);}
        CompileShader(ShaderFile.append(".fsh"), GL_FRAGMENT_SHADER, Stemp[2]);
        glAttachShader(ShaderVariable, Stemp[2]);
        std::cout << ShaderFile;

    glLinkProgram(ShaderVariable);
    glGetProgramiv(ShaderVariable, GL_LINK_STATUS, &TempValue);
    if (!TempValue) {
        std::cout << "ERROR: Cant link shaders";
        glGetProgramInfoLog(ShaderVariable, 512, NULL, Log);
        std::cout<<Log;
    }
}

Here is main code:

#include "main.h"
int main()
{
//GLFWInitialization:
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    ResetWindow();

    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
    {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }

    glGenBuffers(1, &VBO);
    glGenVertexArrays(1, &VAO);

    CompileShaders("Data/Shaders/ui", 0b00, MainUiShader);

    while (Window) {
        if (glfwWindowShouldClose(Window)) { glfwTerminate(); return 0; }
        glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        glBindBuffer(GL_ARRAY_BUFFER, VBO);
        glBindVertexArray(VAO);
        glBufferData(GL_ARRAY_BUFFER, sizeof(position), position, GL_DYNAMIC_DRAW);

        glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 3 * sizeof(float),
            (void*)0);
        glEnableVertexAttribArray(0);

        glUseProgram(MainUiShader);

        glBindVertexArray(VAO);
        glDrawArrays(GL_TRIANGLES, 0, 3);
        glfwSwapBuffers(Window);
        glfwPollEvents();
    }
    
}

ui.fsh:

#version 330 core

out vec4 FragColor;

void main()
{
    FragColor = vec4(1.0f, 0.5f, 0.2f, 1.0f);
}

ui.vsh:

#version 330 core

layout (location = 0) in vec3 position;

void main()
{
    gl_Position = vec4(position.x + 0.5, position.y, position.z, 1.0);
}

(All variables definited correctly, openGL initializated correctly, but if you need something I can send it, or I can send full project).

So I started writting this code from guides, it is can draw 1 triagnle. This triangle should be orangle colored but it is black colored because fragment shader don’t work due to this problem and I have no idea why this happens.
