Fingerprint Reader Issue when Charging

I know that a lot of people have had issues with the finger print scanner and home button, but I didn't see this mentioned anywhere.

When my phone is charging, the fingerprint reader doesn't read my fingerprint properly. It can tell that I have a finger on the scanner, but returns "Try again" and then fails. Is this an issue others are having, or should could it be an issue with the USB-C cable I purchased?

Thanks in advance.
