What's this error (Tasmota)

I am trying to flash Tasmota into a Kuled Switch. Actually, my second one as the first flashed fine.

After flashing, I get the state from Tasmota, then I try to give it my SSID and MQTT credentials, and it appears to accept them,
then it reboots- as expected, but then it dies. Reboot does nothing including no status.

Any clue what may be happening?
(BTW- after the fifth flash, everything worked).
The following is from a serial terminal program (Termite).
