How do I make something that worked before to work again?

[Windows Central Question]

So I had driver that used to work properly,next day it just stopped working and now It does not work for more than month.
I tried to reinstall,start as admin,check if it is blocked in anti-virus

nothing worked and restoring would delete too much of my stuff.

Hi I ve experienced very weird issue with external sound card drivers that I can not solve in w10.
It used to be in hidden icons after start-up but now It is gone. I also can not activate It directly. I tried to reinstall it 4-5 times did not help. Fun and weird part:External sound card still works.[meaning i get sound from speakers] What I can not access is the UI where you can set channels/microphones etc. I had to reinstall real-tek so I can use microphone It is not core of the issue in any way because this problem was there before old drivers installation.

I'm running out of ideas and re-installing my windows is not option .
