If /dev/sda uses MBR, it doesn't really have a UUID, it might have a
serial number. If /dev/sda uses GPT, it has a UUID and it should have
a UUID and it shouldn't be removed. A UUID doesn't just somehow
accidentally transfer from one fs volume to another, or from an fs to
a partition table. I think think needs more troubleshooting, rather
than bringing out the hammer before the problem is identified.

Feel free to post the results from fstab, and blkid.

It might also be useful to see the output from journalctl -b -l -o
short monotonic, from a boot that fails, that also has kernel
parameter rd.debug set.
