Sometimes attempting to boot

Hello everyone, I have a 2017 MacBook Pro and recently I am unable to get it to work. Most of the time while attempting to power on I get nothing but the trackpad being able to click (backlight is off) and sometimes it'll get to the FileVault login screen and the progress bar will progress around a quarter of the way and the machine will shut down (upon attempting to boot into verbose it appears to kernel panic for AppleKeyStore). I can't get into recovery either as it just shuts down. What are some steps I can take to diagnose this? Thanks! (I have the tools required to take the bottom cover off)
