Dead Lora Module SX1262

Well, egg-on-face time. I left my Heltec V3.1 module running bare on the patio with antenna, PV panel and 18650 cell attached. A surprise rain shower dampened it a bit. Now when I start it up, the ESP32 starts fine, BLE comes alive, but I get the Critical fault #3 on the display. No Lora radio detected. Anything I might do to overcome this, or is it permanently dead.
