Problem progression starting with dash blackout, ABS and trac control lights are on

Driving down the highway, the digital portions of my dash go blank, but track control and ABS lights come on, first thought is alternator has gone and get in turning lane to get off the road before battery is gone. My turn signals nor hazard lights worked, but my headlights and brake lights did. When I stop to wait for the green turn, my dash and everything comes back. Light turns green, I press the gas, and dashboard blacks out again, with the same trac control and ABS lights on. I get pulled into a parking spot and turn the car off to see if it'll reset. At first, I thought alternator, but my engine never lost power (you and I both know you can feel when that V8 is running on the battery vs the alternator). When I started the car, everything was normal. I drove the rest of the way home, and it didn't happen again. I drove back and forth to work for the next 3 days (50-mile round trip), came up with Covid on Friday, and only drove twice during that time. The first one was about five miles in total, and the second was maybe 2 miles. On that 2-mile trip it happened again (please see the video attached). The first time, I at least had headlights and brake lights, and I figured to drive it until the weekend since I had already been out of work too long, but without brake lights, I knew it wasn't safe to go down and back on a very busy section of I-4 into Orlando.
Last night, I pulled all the fuses and checked them, in the engine box and the interior. On my multimeter, my battery tested at 1.6v after I reconnected the battery. So, I used my wife's 2018 Camry to jump off my Lincoln. The Camry measured 12.6 volts while turned off and 13.6 while running, and my battery did too while the Camry was running and hooked to mine. I realized that my dome light was on after hooking up to her car. I let Camry run for 5 minutes or so (long enough to smoke a cig.). I turned on my car and it started without a problem, but the dome light went off and the dash went away like before, but without my pressing the gas. I unhooked my wife's car and let mine run for roughly 10 minutes trying to see if it would charge the battery. I moved my wife's car and realized that hers was displaying that the airbags were offline. I turned off her car to reset the computer. It worked for her car. After 10 minutes, I went to turn off my car and open the door. The lights E lights were on the dashboard and the dome light. I got in and pressed the gas, the dash didn't go away again, but the trac control and ABS lights were still on too. I put the meter on my battery while the car was running, and it showed 17.9v.
I am thinking that the alternator back charging so many volts is causing a power surge that caused my wife's car to lose some sensors for a bit, and has blown something in my system as well, but worse because of having been subjected to it for long the minute and a half it took for me to unhook the jumper cables from the other car. I am being told by the place that replaced my alternator that it doesn't work like that, but I know the first rule of electricity, just like the first rule of plumbing. Water runs downhill, and electricity is going the fastest way to the ground, even if it is through you. For a 12-v battery to receive that much energy and not blow up. It was 17.9v while idling, what is it putting out with the vehicle accelerating from 30 to 80 while entering the interstate and matching the flow of traffic, not to mention lane changes and passing other cars, that excess power had to bleed off somewhere, and I am thinking it bled off into the rest of the system causing multiple massive(for vehicle components) power surges in components that are close to 25 years old.
In the video, please excuse my language. I get very aggravated when my car is not doing what it should. I think, in this sue happy age we are living in, that the place that installed the new alternator is afraid that I am going to make them pay for this if it turns out to be the alternator causing the rest of the problem, but I just want to get my vehicle to work how it should. So, as someone who has nothing to worry about as far as responsibilities for this repair, please shoot me straight. Am I way off about the alternator being the root of the problem, and if I am not off on what I am thinking, what other components could have been fried by this? Also, I tried to add a video, but it doesn't appear to have been uploaded.
