So, in my case I clean installed macOS 4 times (once when Catalina came out and 3 times trying to fix a display issue) and finally turned it in for repair. Apple clean installed Catalina again and gave it back to me. But all the time, the fingerprint was left in the storage and so Touch ID wouldn’t work any longer. I took it back to the store and they couldn’t do anything about it but swapping the entire board. This fixed the Touch ID issue since there was a new T2 controller on that new board and also finally fixed my display issue
