The title explains it all, really.
I was playing a game (Lethal Company, public beta Version 55) and since it was crashing, I decided to update my drivers using the CCleaner Driver Updater. After that was all said and done, I restarted my computer, only to find that my audio had completely disappeared. I have tried many methods, looked up countless solutions, and none have worked. I will still follow the solutions I have already done in case of any mistakes.
This seems to have also messed up my Windows search bar, as I cannot open any location in System Settings other than the Settings home page if I try to open it up through the search bar. Other Windows features such as updating through System Settings and screenshot tools have been broken as well.
Any help is appreciated.
