IF you are running High Sierra or later and IF you have Time Machine enabled and IF only have one OS on your system drive, you do not have to go to the Apple Store to restore your system to an earlier state within the last 24 hours.

Using APFS Snapshots, you can be up and running in a few minutes. If any of those three conditions are not met, it won't work.

Did BIAB crash your system? I don't know but probably not. Can't test a crashed system, though.

I have had to use Snapshots many times over the last 18 months. I do audio restoration among other things and a corrupt header on a file can totally screw everything up as can a corrupted Launch Items file and so many other things.

Being able to restore completely in a couple minutes as opposed to many hours via a Time Machine restore ... when Time=Money, a waste of one is a waste of the other.
