Since this is not a generic issue that we can reproduce at our end, we will need someone to look into your machine to figure out what is going on here.

Maybe it is generic, apparently. Same thing has started happening to me, too. The crash actually freezes my Mac, and having to reboot is starting to get a bit old. Fast.
I can hear my fusion drive whirring louder and louder when it locks, so it may be a memory error. I've clean reinstalled both Illustrator AND High Sierra in an attempt to fix it, but no dice.
