YCM Semantic Completion not working

[MATHS MOD]

[WINDOWS 11]
I have read the FAQ (tried ctrl+space, fails badly in all modes of vim) and modified .vimrc multiple times without success. I am using GVim 9.10821 on windows and downloaded YCM today. I am using Python 3.13.1. I used :YcmDebugInfo and it shows no problems. Earlier I used to see RunTime error in red on starting a py file but it is no longer the case. I have tried a minimal setup which fails:

syntax on
set guifont=JetBrains\ Mono\ Light:h10

set nocompatible

set plugin indent on

call plug#begin('~/vimfiles/plugged')
Plug 'ycm-core/YouCompleteMe'
call plug#end()

let g:ycm_global_ycm_extra_conf = '~/.vim/.ycm_extra_conf.py'
(Called using vim -u minimal.vimrc test.py)
On Running :filter youcompleteme scriptnames

output:

 12: ~\vimfiles\plugged\YouCompleteMe\plugin\youcompleteme.vim
 27: ~\vimfiles\plugged\YouCompleteMe\autoload\youcompleteme.vim

 28: ~\vimfiles\plugged\YouCompleteMe\autoload\youcompleteme\filetypes.vim

Played enough with g: settings.

Testfile I made:

import os
import jedi
print(os.name) <checked once>
x = 12
y = x * x
dinosaur = x + y
print(dinosaur)
os.

Only [ID] types are visible and they autocomplete correctly. Also filenames using / autocomplete Semantically, it's only when one is trying to code properly that it bites.

Output of :YcmDebug
