[HELP] Dell XPS 15 7590 OLED - no audio after OC try

I was trying OC for the first time because I miss filevault.

I'm on a Dell XPS 15 7590 OLED, Intel i7-9750H 2.60GHz, Graphics 630, ALC298, Clover 5119.

I followed the guide for OC, tried to boot from the USB and it didn't work. This was the error:

Since I didn't know how to fix it I just tried to boot again with Clover. It did but no audio device found. I tried every possible old configplist but nothing and if I try to change the audio injection it get stuck on boot.

I also noticed that I cannot disable the lockscreen password anymore, seems like something got corrupted in the system with the OC try. Could that be it? Should I use a time machine backup?
