The error "File system verify or repair failed. : (-69845)." indicates file system corruption on your MacBook Pro's SSD. To fix it, try the tips below:

① Rerun First Aid in Safe Mode

Try booting your Mac into Safe Mode and running First Aid to repair your Mac again. Safe Mode can prevent third-party software from intervening in the repair process and clear system caches.

② Repair your Mac with fsck

You can also opt for the alternative method - fsck - to repair your internal drive. Reboot your Mac, then immediately press and hold Command + S until you see the Apple logo. After that, execute the command below to run a system check.

/sbin/fsck -fy

③ Format your startup disk and reinstall macOS

If the error 69845 persists, consider reformatting your startup disk and reinstalling macOS. Note that this will remove all data on your Mac. So ensure your data is backed up before proceeding.
