System crash from cold boot up?

[lieiti]

Hi all, when I shut down my computer and then start it up fresh next day, I get an immediate crash and automatic restart. Then it boots normally. Afraid one day it may not reboot normally so trying to solve the issue now before it gets any worse. Any ideas as to what could be causing it from this crash report? Unfortunately it's Greek to me.

BIG thank you to all the tech geniuses!

com.apple.iokit.IOHIDFamily and com.apple.driver.AppleFDEKeyStore seem to be involved. IOHID is about hardware drivers, specifically input devices (‘human interface devices’), and AppleFDEKeyStore is, I suppose, about file-system encryption. Have you checked your hard drives for errors with Disk Utility and are you using FileVault? Are you using any additional peripherals and third-party drivers? You may want to create a report with EtreCheck and paste the result here.
