Failing to get any PyOpenGL functions working, keeps getting error 1282 invalid operation on Windows

Question

I've been searching in Google and Stackoverflow for days now trying to solve this peculiar problem... tried out over 50+ ways suggested by the OpenGL/Python community. My 1st time trying to use PyOpenGL within PyCharm IDE... or Python cmd line.

• Windows 10 OS
• no GPU, just Intel UHD 64-bit graphics latest driver and tested OK with OpenGL v4
• installed Python 3.10
• installed latest pyopensl, pygame, etc into PyCharm and C:\Python310\
• even tried installing PyOpenGL via wheel file... PyOpenGL-3.1.6-cp310-cp310-win_amd64.whl and PyOpenGL_accelerate-3.1.6-cp310-cp310-win_amd64.whl

The following simple std codes I got from the WWW community keeps throwing...

OpenGL.error.GLError: GLError(
    err = 1282,
    description = b'invalid operation',
    baseOperation = glGenTextures,
    pyArgs = (
        1,
        <object object at 0x000001E4412E72A0>,
    ),

Here the full codes...

I narrowed down to the "1282 invalid operation" complaint from running ANY glXXXXX() functions. If I removed any glXXXXX() function, it will complain the next glXXXXX() until all of them are removed. I cant even have the simple... texid = glGenTextures(1)

The "earth.obj" I have all its mtl, texture, bump 2D jpg files in same dir as this py file. I tested these 3D/2D files using 3D viewer online to be OK.

Anyone can please give some pointers what is wrong with my OS or graphics driver or packages? Thanks a bunch!
