Default Bmw 428i n20 valvetronic power supply relay short to earth - 10-24-2021, 08:29 AM

I drove my car last time to the store and I did small pull, car Rev up to 4k rpms and acted like 2step so I let of my foot from gas pedal and red warning pop up to pull up to side immediately so I did. I shut down car engine and restarted it,and i notice misfire so I pulled up in some parking to restart engine engine again and it didn't want to start for few minutes after some time I got it started. I drove car back home and scanned it with jb4 to find out misfire at cylinder 4 and multiple cylinders and one code 1f0514 valvetronic power supply relay short to earth, I also noticed that my 4 cylinder coil pack was little bit melted so I ordered 4 new coil pack and spark plugs but misfire didn't go away, so I'm pretty sure it have to be with valvetronic code but I don't know where to start I checked all connections and fuses nothing wrong with neither of them can someone help
