locked under an unknown email acccount

mackbook pro 13" 2020 i7 2.3 32gb 1 TB

After i purchased from craigslidt i was able to use my itune account, after i updated the software i was having some issues, thats when i decided to wipe it clean and use the web to download the latest software, however i am being told its locked under an unknown email acccount with i dont know the password. what option do i have, can you flash the memory or fix the logic board. please help if you can, otherwise its a $1400 door holder.

Thanks
