First time upgrading cpu and I fucked up

I have a pretty old PC which I got from my cousin a few years ago. It has a AMD Ryzen 3 pro and I just got a Ryzen 5 4600G. When I installed the processor the lights which indicate the PC is on turned on but there was no display or any signs that I will be able to use it, after looking online I found the problem, I did not update my BIOS before upgrading which left me no choice but to reinstall my old processor. I took great care in handling the processor but when I installed the processor my PC wont turn on, no lights or any indication of life.
