I've recently tried APO then uninstalled it after using it for a bit and now my sound has completely gone to shit since,

I have tried every solution, Resetting Win11, uninstalling it from device manager, and all,

But it seems like there's no possible solution to this shit whatsoever. I use this laptop mainly for music production and this has completely hindered me from it. I cannot work with my sound being like it has noticeable reverb/echo and distortion in it.

Does this mean I have to buy a new laptop because of a mere app? that ruined my system sound for good.

  DolbyAPO swc (as shown on your screenshot) isn't Equalizer APO. It has nothing to do with it. A quick search on the internet points to Lenovo although it can be Windows 11 itself. I don't have this APO installed on my Windows 11 laptop.
