The keyboard is sinking in the middle

I don’t think I’m the first person to encounter the keyboard sinking in the middle. Does anyone have any thoughts?

FW13 AMD 7840U

There’s def stuff on the 16"

Is this a DIY or pre-build and have you contacted support directly, if you are unhappy?

Maybe you are. I can’t find another post for the 13" over 3 years ???
