Left stick sutck fowards after battery leaked inside

Hello! First of all, thanks in advance to the experts in this forum!

I'll keep it simple. A battery leaked inside the controller and this is how it looks

So the problem is that the left stick is stuck on forwards/up position right when I plug it in. Even after desoldering the stick from the board, it shows on the controller tester that it is in forwards position.

This is the controller in the tester software: https://streamable.com/8z9r05

This is under the left stick:

For comparison, his is how it’s supposed to look brand new (under the stick)

Is there anything I can do to fix this? I have the tools to solder things
