Prius ICE won't turn on. Limp mode.

Hello I put some cataclean in the gas tank because my catalytic converter is getting worse. I was hoping I could buy some time to replace it which in hindsight I won't ever do again.

So my Prius the past couple days has been driving like the Cat was clogged prior to me doing this. It'd lose power Going uphill and have a sound like a paper plate into a box fan flapping sound when I tried accelerating. It could still get to normal speeds it'd just have that tapping sound which fit evey online description of what a clogged Cat does and I have both codes for my catalytic converter.

I realize this was all A HUGE mistake and if I could go back in time I would but that doesn't help me now.

So while driving i suddenly lost power and it went into limp mode. I'd usually always drive fast enough to where that sound wouldn't present itself but was hoping the cataclean would do its job so drove at normal speeds while I was beginning to go uphill.

I realize this was all a huge mistake now so please don't lecture Me. I just REALLY need help now because it won't go into drive.

I have error codes P0456. P3190. POA4B. P0401. P0420

The only error code I had was A red steering wheel with an exclamation point and the check engine yellow symbol which I've had periodically since I owned it because of the catalytic converter code.

I've unplugged and plugged it in several times and have never changed the 12 volt battery so I believe that is drained too now because its acting like it's possessed. It'll make a whirring sound when I try shutting it off and the yesterday when I connected the battery terminal back In it immediately turned on like I had just pressed the power button. When I'd press the brake pedal it'd flash all kinds of codes and would intermittently go in and out like a dead battery would. So I believe the battery was already low but me trying to troubleshoot it drained it completely.

It's an absolute nightmare and I've been using the car to make money and now I'm completely screwed if I don't get it going.

Any help would be beyond appreciated and trust me if this ever happened again I'd change the Cat immediately
