Trying to diagnose a problem. Do I need a new charging daughterboard?

So last October my Galaxy S8 and I fell into a river when my canoe tipped. The back was cracked so no water resistance. Three weeks in a bag of silica and 6 months sitting in a drawer later, the phone turns on and everything works, except occasionally when I plug in the charger the device will shut off, and the vibrator will spaz out for a second. After being off for like 5-10 seconds, I am able to turn the phone back on without issue. I have not had this problem with wireless charging, and if I plug in the cable and this issue doesn't happen, the device charges up fine.

When I first tried turning on the phone even after it sitting in the silica bag for a few weeks, it said there was water in the port. The next few times I tried turning it on, it still said that, and it wouldn't let me use the port (but I could wirelessly charge). Now after sitting in the drawer for months, it does not say there is water, but this happens.

So, does this sound like something a new charging port daughterboard would fix? Or does it sound like something else is going bad, or is there perhaps still water inside? Again, the phone works fine otherwise- I've put some hours on it to test it. Just this charging issue.

I do have another phone I am using by the way.

So what do you all think?

Thanks!
