Unexpected entries in journalctl. system only boots randomly

For this, see:

This is the fist time I see ‘reboot-for-bitlocker’ in /efi/loader/loader.conf.
I cannot find any reference to this option in man loader.conf and I guess it must have gotten in there by mistake (?).

What is the content of your /etc/fstab ?

Also, are you using a seperate partition for /home?
