Data recovery after unexpected crash

My mac crashed today, and it is as if it reverted back to October 2. Every single file (including backups/saved states/iCloud files) between October 2 and today (October 10) has been deleted. Anyone know if this is something that can be fixed or am I completely screwed?

Running: macOS Mojave version 10.14.6

Tried booting up in safe mode, and every time, I just had a frozen screen.

No other issues with mac besides the random time jump.

No, I don't have an offline backup saved. I do that once a month usually, so the backup I have offline is Sep 30.

You can not make data magically re-appear —Use an alternative backup to restore your data.

If you do not have one, then you may come to realize your backup strategy is inadequate—do not wait for a catestrophic failure to get the 'backup religion.'

3-2-1 Backup Strategy: three copies of your data, two different methods, and one offsite.

Did this happen after the 2020-005 SecUpd for Mojave?

Try reinstalling this in Safe Mode, but not using Firefox...

Safe Boot, (holding Shift key down at startup).
