MacBook Pro keeps crashing

I accidentally spilled water on keyboard of my MacBook Pro, I turned it on after 4 days of drying. I reinstalled the iOS by going in recovery mode and no data was lost.

however it only turns on if ANY key is pressed immediately after pressing ON key, if a key is not pressed then it crashes immediately. If I keep a key pressed then it stays on for as long as I need to use it. Also It is working a bit slower than before.

i have done hardware diagnostics, no issues identified, also did Nvram settings etc.

anyone knows how to fix the issue or what could be wrong that it requires a key to be pressed all the time?

thanks
