New Xiaomi MI9 SE - Problem with fast charging + USB connection to PC doesn't works after update to 12.5.1

[Vende123]

Hello everybody
Im writing to you because I have problem with my phone after update to newest version MIUI 12.5.1. Im so frustrated and dissatisfied about xiaomi updates because every time when I tried update I got some bugs.
At the moment I have problem with my battery charging. I noticed that my xiaomi always charging normal (its 4 hours of normal charging) , not in fast charge method (2h). I tried other battery charges from my friends and its also doesnt work. Previously it was fine.
Second Problem is with USB connection with PC. I can't even do backup of my phone for try downgrade my phone etc. Nothing appear when Im trying to connect to usb, just like normal charging.

Could u help me resolve that bug? I very like xiaomi but sometimes updates are frustrating.
Thanks

@Vende123 This is the forum of a CUSTOM ROM. Are you using this ROM?

No, Im using global version.

So it can't be an issue of this ROM here. Please report it to Xiaomi official forum.
Thank you.
