I can crash without any mechanical failure whatsoever on my bicycle.

I thought the whole idea of tying and soldering the spokes on a wheel build for a track bike
was essentially to prevent the possibility of a broken spoke flopping around and possibly locking
up a wheel, so I'm gonna go with "could have been the cause, or could have been a result of the crash".

Because I've managed to crash and break one spoke in a rear wheel as a result, too.
