Couldn't add fingerprint

[zeyarmoelwin1998]

I flashed miui 12 and sensors didn't worked so I flashed persist img from fastboot and sensors work but fingerprint failed.. At first, my fingerprint worked well in every rom.. After flashing persist img from twrp, my fingerprint is like that in every rom.. ( I forgot to backup persist before flashing persist img ).. How can I do? My country doesn't have official service support and no warranty..
