2020 Toyota Camry Equipment Problems

So a few months after installing the pedal commander chip my Camry out of nowhere began flashing warning symbols and messages and the engine was reduced to about 5% power. Pre-collision braking was down, ABS was down, lane assistance was down, cruise control was down and it also said “Engine Reduced Power”, please see dealership! So I parked, turned off the car and disconnected the battery for about 10-15 mins. When I reconnected the battery and started the car everything was fine and there were no codes/warning lights. So I thought it was a glitch. Then like 3-4 days later it did it again immobilizing me outside of a clients house to where I had to get it towed. I then thought to unplug the chip and see if that did anything and of course once I did it started up and drove fine with no codes, for about a month or so. Then it gave me all the same codes as before but now without the chip installed. Did an oil change with new filter, replaced the starter cause now it wouldn’t start at all or turn over. Once I replaced the starter, I was able to get it started and drive it a few times over the course of 3-4 weeks at the time I wasn’t driving it that much. But then all of a sudden it stops starting again and now gives me all those codes again and now my Camry has been immobilized for the past year, basically all cause of the accelerator chip.
