APO 1 stopped working after years of great cooking. Any hope?

After a long cook, my APO 1 suddenly stopped working. No power at all - no display, no oven light, no connectivity to the app. It’s like it bricked. I’ve verified that it’s not the outlet, and I’ve given it plenty of ‘rest’ time unplugged.

I’m having trouble figuring out whether anyone has fixed this issue or has troubleshooting steps. I see several threads about replacing the fuse but I think they all had power, just no heating.

Took off the back and found some damage. No idea if this is the cause or how to fix it if it is.

Guessing this isn’t the cause, per this video that’s just one of the heater connections.
