!!!PLEASE HELP!!! Macbook Pro 2019 keyboard+mouse pad malfunctioning..?

!!!PLEASE HELP!!!

So in around October, soda was spilt all over my keyboard. It was a lot of soda and it was spilt all over my keyboard. I had no idea what to do so I just cleaned up the soda with a paper towel, shook it a couple times upside down, then wiped it again. After that, I blowdried it with my blow dryer, left it out in the sun for a couple hours, then set it upside down for a while. It wasn’t plug in during any of this either. After a while I sort of just put it away because I had no idea if it still worked, and didn’t have time check. Then a couple weeks later I open it back up and see that it was working perfectly fine, so I started using it again. However, after using the Macbook for a while, the keyboard and mouse would randomly stop working. Usually I would just turn off my laptop, flip it upside down, shake it, then it will start working again. However, now it’s been turning off more often then normal.. This time however, I can’t seem to get the keyboard or mouse pad back on.. I’ve put it upside down for a while, leaving it off to the side closed for a couple hours, and even cleaned the keyboard and still nothing happens.. I’ve entered recovery mode and chose the option telling me that my keyboard or mouse wasn’t working.. Then, it would ask about turning off FileVault..? I don’t know what that does and don’t know for sure if that’s what I need to do.. I don’t know if this is because I’ve had the laptop for a year, or because the soda did something to it, but the keyboard and mouse are seriously not working at all…

!!!PLEASE HELP!!!
