Try the Following:

A. Reset the SMC and your NVRAM:

Aplies to Intel-Based Macs Only). Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Keyboard and Touch ID) become manipulated, technically. So, reset the SMC and NVRAM

B. Go Here:

• If Touch ID isn't Working on Mac - Apple Support

C. Boot in Safe Mode:

In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another use of the keyboard and Touch ID. Go Here: Start Up your Mac in Safe Mode - Apple Support

In doing so, you with have something to restore store your Mac from from, should anything go wrong with the reinstall.
