1. Flash MiUI EU Weekly build
2. You can try OrangeFox though there shouldn't be any difference...
Or
3. Flash Fastboot ROM and start again.

I used orangebox recovery and it works anyway thank you very much for your answer

Be careful when flashing new rom
the dynamic partition will be a pain in the ass if you don't carefully install new rom
