Contacts application won't open.

Thanks to my Unix engineer at work, his idea was to go to System Preferences from my computer>Internet Accounts, then turning off (unchecking) any accounts that were tied to Contacts. Once I turned off Contacts from those accounts, I was able to launch it, although it was still stuck on the bad card for a while. But after a couple of minutes of the spinning ball, it loaded and I was able to delete that card. After that, I could quit it and launch it again and it starts right up without issue, even after turning Contact back on in my Internet accounts.

One thing I did before getting a hold of my Unix engineer, was to go into Contacts via the web on iCloud. I was able to import the .vcf cards I wanted and it served my purpose, which happened to be to put a range of phone numbers into one contact card and then be able to block that contact from my iPhone contact list. I've been getting varying spoofed calls throughout the day which have the same area code and prefix, but different 4-digit numbers at the end. Since the last 4 digits changed each time, I found a forum that helped me put a range of them into one contact. However, DO NOT do this by exporting from Outlook - the .vcf file is a little different than the one for Contacts. I would also break them down by just the first of the last 4 digits so that instead of having a contact card with 10,000 work numbers, I have only 1000 per contact and create them as needed. Here is the page with the instructions, if anyone should run across this forum and is interested:
