Cranks but no start
Each of these codes are all showing pending, stored, and permanent
fried ECU or bad engine harness?

Yeah I have. So here’s the thing it was running and I had grounded out the power wire to the bpv solenoid and the car then shut off

Since we have malfunctions in all different systems P00, 02, 03, 04 that can only mean two things like you said bad harness(even bad ground) or bad ECU.
To test out is kinda simple. Find a connector like BOV solenoid, easy to test and it's 'malfunctioning', then find terminal for that connector on ECU connector and test for continuity, if continuity is present then bad ECU but if it's absent then bad harness.
You got a friend with another Genesis that can let you borrow his ECU to test?
BATTERY TERMINAL OFF

The easiest way to completely drain the capacitors(and remove any energy from the car and all the control modules) is by removing the battery and pairing the positive and negative terminals of the car. What happens is what manufacturers call a Hard Reset. I seen techs do it that way at my dealership.
Can't hurt to try.

You got lights on dash and only a couple codes, so it's not too bad. Think about the codes you have. Your ECU is reading ERROR when trying to read RPMs.
The key to the big question is testing for continuity between failing part and ECU connector.
Rodents are mfs.

I know it’s not rodents because I was the one that caused the car to shut off. I was using a power probe to try and find what I thought was a possible short on the positive cable to bpv solenoid and when I put the probe to the cable I basically ground it out with the negative button. This causing the car to die.
