It worked, Thank you!For all those having problems flashing PE 11 (@newbo1211 , @arkansis ), here's a quick guide:
Clean flash global 12.0.4.0 (lmi_global_images_V12.0.4.0.QJKMIXM_20200923.0000.00_10.0_global_18b68d3e34.tgz) with MiFlash.
After flashing 12.0.4.0 go straight to fastboot mode and flash 1206 chinesse TWRP (twrp-3.4.2b-1206-xiaomi10-cn-wzsx150.zip):
> fastboot flash recovery twrp.img
> fastboot boot twrp.img
After that, wipe data > reboot recovery > and now flash global 12.2.1.0 from here (miui_LMIGlobal_V12.2.1.0.RJKMIXM_35857b638b_11.0.zip).
Reboot recovery.
Now flash PE11 > success!
This will provide you a clean fresh start, zero issues found so far if you follow my steps.
