Damn, so much for the easy fix. Something you could try is a full manual erase and re-flash of the ESP32 via USB and CLI. Make sure the ESP32 is configured properly for your hardware. All the relevant stuff is here: https://github.com/skot/ESP-Miner

On an older FW version, I did have one get "stuck" and doing that helped. I don't know if something gets corrupted, or magic gremlins, or whatever, but it fixed the strange behavior.
