Today the TouchID on my MacBook Air suddenly stopped working. Based on this Apple's page, I tried all of the steps, including wiping the sensor, different fingers, restart, adding another one, etc.
None of them work. The problem is that the sensor seems no longer detecting the fingerprint. I removed one and tried to add a new fingerprint, but it did not recognize my finger.
My MacBook Air is 2020 model with M1 chip, so SMC reset does not work, either.
Is there anything that I can do to fix the problem? The city I'm currently in has no Apple Store.
UPDATE
This happened again, and it seems something is wrong on the software.
