As per the show tech, the switch flash does have 2 crash files, but as Pierluigi said that we don't know that these crashfiles belong to recent crashes or these are some old crash files as the timestamp gives us wrong info.

Also one more thing to notice is the show version output which says:
System returned to ROM by power-on
So there are chances that the switch went down because of some issues with power. So get the power supply and the UPS checked.
In cases of crash due to internal software errors the show version says something like
