If we're connected to perforce then hit autogenerate and bake, we get a crash almost 100% Of the time at the end of the bake when the system is about to write out lighting data.

The only workaround is to put the Editor Source Control into Work Offline, manually check out the lighting data assets, then we can bake 100% with 0 crashes.

This has occurred on any 2018.2 version. This did not occur on 2018.1.
