Question TWRP isn't working correctly. - Xiaomi Mi 11 Lite 5G

Hello XDA Users!
This week, i've been facing a problem.
I tried to use TWRP to flash some ROMs, and do others stuff.
Except that, when i try to use TWRP, i encounter some issues.
1st. My Internal Storage is detected as 0MB. (I tried formatting data, switching to ext2 then back to ext4, and once doing this IT is detected, but after a restart, TWRP remembers nothing about my internal storage.
(Note about the 1st: I also can't mount the internal storage partition on my computer, i tried it on both Windows and Linux. Well, it mounts,
but the partition "Internal Storage" size is unknown, type unknown, filesystem unknown, and can't copy anything or read anything.)
2nd. Since my internal storage wasn't working, i thinked that i could take my SD card and it'll work! So, i taken a SanDisk of 8GB SD, that works perfectly fine on my computer, and i used it for years. So, i open the SIM tray, and put the SD into the SDCard slot. I restart my phone into the OS, detected fine. I go to TWRP, and same issue. SD storage: 0MB.
3rd. My battery isn't detected in TWRP, no battery information whatsoever. It isn't that important to me, but i guess this can mean to its not really working fine?
Note: I tried downloading multiple time the TWRP for my phone, and all the images we're exactly the same, except for the file name itself. I tried booting on the different images, checking if its not corrupted, and all the images are OK.
Details about my phone in case you need them:
Phone: Xiaomi Mi 11 Lite 5G Global
Model: M2101K9G
Storage: 128GB
Current OS as now posting this post: Android GSI made by Google with Android 12 (https://source.android.com/setup/build/gsi?hl=en)
Sorry btw for my bad english, i'm french.
So... anyone knowing how to fix my issues with TWRP?
Also, i know that TWRP for the renoir is still in Developement, so i except to not get awnsers.
[Note as of 5/11/21 at 14:13: I got Pixel Experience to flash without TWRP, and that was my only use for TWRP, so, i won't take attention anymore to this post. Please, go to others posts that really ask for TWP help..]

Le seul problème que j'ai avec ce TWRP et que je ne peux pas monter la carte SD. Mais c'est un problème connu. Tu suis bien la procédure de flash de ce TWRP et en particulier d'effacer les données seulement après l'installation de la rom.

The only problem I have with this TWRP is that I cannot mount the SD card. But this is a known problem. You follow the flash procedure of this TWRP and in particular to erase the data only after the installation of the rom.

Okay,
J'ai téléchargé l'outil pour flasher TWRP pour bien le Mi 11 Lite 5G, mais, il s'avère que c'était EXACTEMENT la même chose...
Ce qui fait que j'ai aussi malheureusement les même bugs qu'avant, donc 0MB.
J'ai quand même esseyé de suivre le tuto, et au bout du rouleau, j'ai formaté ma data, et changé mon filesystem de la partition Data de ext2 a ext4, et EFFECTIVEMENT mon internal storage était bien reconnu!
Mais.. windows ne veut rien savoir.
Je n'ai pas plus donc flasher de rom, ce qui fait que actuellement, j'ai formaté mon internal storage, et j'ai changé son file system, pour au final... rien xD
Je reflasherais dans l'aprem une rom .eu si je trouve aucune solution.
Je vais te joindre un screenshot de ce que windows me dit
Sinon, passe une bonne journée
