Android Debug Bridge "Unexpected error"

Hey, I know this has been asked a million times but none of the other issues seem to be what I’m experiencing.

I’ve got a latest gen 4k Firestick. I’ve enabled ADB debugging on it. When I try to connect with the Android Debug Bridge integration I get an immediate error at the top that says “Unexpected error”. Looking at the logs, it seems like it may be related to the key file that’s supposed to be auto generated if left blank, but I’m not sure. Any ideas? Below is the log entry:

Logger: homeassistant.components.androidtv.config_flow
