Did damage to the fingerprint reader break iPhone 8+ charging circuit?

My iPhone 8+ screen is cracked. It seems to have been struck at the left edge of the fingerprint reader. I want to fix the phone but am concerned about the reader being damaged as i understand a replaced reader will not read fingerprints again unless it is replaced by Apple. A key symptom is “The phone will not charge”. I plug in a cable but the screen stays blank. SO, what is the likely hood i can reuse the fingerprint reader when replacing the cracked screen?
