Fingerprint not working after upgrading to IOS11

After upgrading to IOS 11, the fingerprint on my iPhone 6s has completely stopped working. After updating the IOS, my fingerprints were deleted from the phone, the option to add fingerprints was blocked and my device says that it is unable to activate Touch ID on this iPhone. Pictures attached below

Here, the add fingerprint option has been disabled and my fingerprints deleted.

The message I get when I try to enable unlock iPhone using with fingerprints.

The message I get on restart
