Time Machine keeps stopping at about 56%

I have Mac Studio running Ventura OS13, I have an External Drive plugged directly into the Mac, and it never gets past about 56% (which it says is around 13Gb) backing up before freezing. When I come out and look, it hasn't saved any of this 56% of backup (and that figure is incorrect, there has been a much bigger amount of changes than 13Gb. The disk is not full, it is formatted correctly (AFPS I think it is), I've uninstalled antivirus and not running anything in the background.

Please advise and help... thanks, Matt.

Mac Studio, macOS 13.0

FWIW. I've seen this when there was one or more Time Machine local snapshots on my Mac that is/are corrupted.

Once I removed them and started a manual TM backup, the process completed successfully. Might be worth a try in your case.

The easiest way to "remove" them is to temporarily switch TM from "automatic" to "manual" backups. You can do this via System Settings > General > Time Machine > Options ... > Back up frequency.

Leaving it in manual, for about 10-15 mins, should do the trick. I suggest that you leave it in manual and run a manual backup to verify that it completes successfully, before resetting it back to automatic.
