Warnings problems of the 2025 Toyota Corolla

I was driving west bound on i40 with the adaptive cruise control, and lane assist on at 75 mph. It was around 8:30 pm when I seen the instrument panel flash, just drop for less than half a second, and then come back up but dimmer, like when the headlights come on, except they already were on. At that point all engine noises stopped and the car felt like it was actively braking. I literally lurched forward in my seat. I noticed that the rpm's had dropped to zero and I didn't see anything on the dash that indicated any warning. All green icons and nothing red. Stepped on the gas pedal, nothing. Tried hitting the cancel on the adaptive controls, nothing. I started turning the car from the inside lane to get to the outside shoulder while shifting the car into neutral to get more drift and tried toggling the key from off to start position and the engine. No rev, no rpm's. Car stalls in the outside lane. I turned on the flashers and then put the vehicle in park, removed the key and then re-entered the key and tried to start. Nothing. Attempted to push the car out of the lane in neutral but I wasn't able to get it to move. A couple semi's go by and I about pooped my pants. Waited for highway patrol to come by and get the car towed. Very fortunate no one was hurt or killed. I believe the automatic emergency braking activated or the electronic parking brake activated? all of the interior systems still had power.
