420A Car stalls but only when I am coming to a stop and pressing the clutch in

I have seen so many forums with this exact problem and none of them seem to be solved, they are also all from 2010s and a little too late to ask questions.

My car seems to be stalling whenever I clutch in but here is where it gets weird. If I am lets say in 3rd gear going 30 mph around 2kish rpm and I clutch in, the car will almost always just die BUT if I just keep the car in gear until no matter which gear I am in, if it comes down to like 1100 rpm and I clutch in, it wont stall. This is the part that really confused me.

I have no codes other than a IAC code P0505 which no matter what I do, I can't make it go away. I have replaced IAC, cleaned out throttle body and even done a smoke vacuum leak test to see if I had a vacuum leak but nothing stood out. I found another thread with the exact same problem and even including the part where if they clutch in at low rpm they don't stall but unfortunately the thread got left unfinished and they went as far as replacing clutch but that did not fix it.

If anyone finds a thread where they solved there stalling problem PLEASE link it to me, this is driving me crazy

Have you checked the connector and harness for the IAC? It's possible to have a loose connection or broken wire.

I have checked the connector and harness for the IAC and it seemed to be fine. The car seems to be acting a bit weird, at points it will idle super high when I clutch out no matter what RPM I clutch out on, it'll go up to 2-3k and then at other points the car just dies. I had a theory because I have already cleaned the throttle body, replaced TPS but that was more for the jerking in gear, it helped a little bit and added a new vacuum line for my egr valve that my alternator might be failing because the car is more likely to die when I put load on it. For example the other day I was testing how it was dying and at points when I stopped and it didn't die but it was about to die and I turned the steering wheel back and forth really fast, it would die. Is it possible that the alternator is not charging my battery correctly and giving the IAC the wrong voltage and keeping it closed at points or keeping it open? Please correct me if I'm wrong as I am just a beginner trying to learn more about this platform.
