Pressing the accelerator pedal down and it was not going, it was just revving up?

Let me note that minutes before my issue came about, my son had tried to get in the vehicle when it was locked which made the alarm go off and so on, I came out and the dash was flashing “theft attempted “ it allowed me to still start it and even move it down the road and then I was pressing the gas down and it wasn’t going it was just revving up, so I pulled over turned it off started clicking and unlocking it to make the “theft attempted” go off, I was successfully doing that, start back down the road again and again, as my foot was already pressing the gas pedal, it stopped actually going and started revving again, so I drifted off the road into a driveway, couldn’t actually go by pressing the pedal I was only able to park it bc every time I’d turn the car off then restart it, put in gear, it would allow me to actually move it for just a few seconds then it would not do anything again and just keep revving up everytime I’d press the gas down, and I had to keep doing that until I had it parked safely. I unhooked the battery for ten mins, I did all the unlocking and locking mechanisms, I’m not even too sure if the two incidents are related but it did start acting up right after that alarm was activated. I have just a basic reader which it’s not throwing any car codes on so that doesn’t help much. Any suggestions?
