That happened to me twice.
What helped in both cases was booting from an SD card and running
The first time it happened I was in real trouble because I was away from home and badly needed the phone. Ever since I have an SD card with the multi boot image in the phone as well (and a text file with that command in the documents directory of the mobian distro) so I can repair the eMMC if needed.

Code:
sudo fsck.f2fs -p /dev/mmcblk2p2
