  • You probably need to try again from Recovery. Live mode means some of the disk cannot be altered, as the system is running from it. I would also ensure your backup is up to date, in case the drive dies completely during this operation.

  • Tried from recovery multiple times but same log every time

  • Then I'd guess one last shot is to boot it from Internet Recovery or a USB stick & see if that makes any difference. If not, then it's time for a new drive, I'm afraid.

I fixed some corrupted internal APFS SSD system drives for a Mac mini and macBook Pro running Ventura 13.2 by making an external bootable verified full-image SSD drive backup of the systems which needed repairs.

The details are posted here in my answer to the "How to fix my corrupted APFS container?" question.
