Re: XPS 15 9570, Fingerprint Reader not working after BIOS update
I have had the same issue since updating to:
Version 10.0.19041 Build 19041 and BIOS Version/Date Dell Inc. 1.17.1
A complete windows rollback solves the problem. Updating again to Build 19041 again breaks the fingerprint sensor.
Based on previous forum posts, it appears there is an issue with intel SGX, however this appears to be more integral to the OS now, and it is not possible to simply update the driver with a different version from intel's website.
Previously suggested forum posts like updating goodix driver, enabling SGX in bios, etc. are not solving the current version of this issue
