Contact app keeps crashing and won't open.

First try this & let us know the outcome please...

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

Is it still crashing?

I have used the safe way to try to get my contacts app to work. It won't. Can you help me?

Maybe, it would be better to start a new topic though so we don't get confused gross talking. :)
