So ? Did you reconnect your device ? For TWRP install you don't need usb anyway. Why that won't work ?
Looks like it´s discussed already. Continue here https://xiaomi.eu/community/threads/miui-13-with-a12.66547/#post-666528
Flash latest official. https://c.mi.com/oc/miuidownload/detail?guide=2 or try custom ROM https://forum.xda-developers.com/f/xiaomi-redmi-note-5-5-plus-roms-kernels-recove.7420/ If i was you i´d search nearest E-waste collection point.
Im not currently on xiaomi.eu but just curious are those Lsposed Shamiko gibberish really needed ? I´m on rooted official ROM and renaming Magisk , using Icebox to hide it when needed and safetynet-fix and i get HD streaming etc.
Factory reset right after ROM install worked for my Mi11. You could try https://github.com/MuntashirAkon/AppManager to check/deny/give permissions for Gmail.
Sorry about that and also wrong place to ask support for that device because it´s MediaTek. (Not supported by xiaomi.eu) You´ll have to go here https://www.mi.com/global/support/contact/
Just my opinion but if possible use linux to install, no hassle with drivers and other wonders of windows. Never had a single problem when installing with linux.
