That error might be the explanation for the difference between cold boot and restart boot. I have zero clue what it means and why it only happens on restarts and not cold starts.
This bug from 2021 with the fix and the comment seems very relevant and it might be the exact same:

Unfortunately I have no idea how to tell if the reboot problem ever got fixed in the last two years after that comment was made.
