Security light flashing, will not start and no electronics

I was putting air in my tires at a gas station. Had to get back in and back up to get to all tires. No issue there. However, when I got back in to leave my security light is flashing and it won’t start.

Hazard lights still work, but but interior lights flash when I turn them on. Locks, key fob, etc, don’t work. If I turn ignition on security light stays on. If I turn key backwards security light flashes.
