Clear system cache

2.- Then booted in Safe mode

3.- Went to settings > App manager > Clicked on Show system apps > Deleted Google+ App and Disabled Google Contacts Sync App

5.- Cleared/deleted Contacts app data and cache

6.-On Contacts app turned off: Apps that can change system settings

7.- On Contacts Storage: Cleared Cache

8.-On Phone app V 1.0: Cleared Cache and Data

9.-I noticed a 2nd Phone app V1.0 by Samsung in my system apps, also cleared cache and data

10: I noticed a 3rd phone app with a diferent icon (my phone is themed) and this one was a V3.0.00.21, also cleared data and cache.

11.- Rebooted and cleared again the system cache from boot screen.

Result: The Phone and Contacts apps by Samsung (Oem preinstalled) no longer crash on startup, no longer crash when used and no longer shutdown the Galaxy S9 Plus with Oreo 8.0 2018 Build and they can be used normally again.

Step 1: Open your Settings.

Step 2: Go to Application Manager or Applications or Apps depending on the model of your device.

Step 3: Slide to or Select All tab.

Step 4: Find and Tap on Contacts.

Step 5: Tap on Clear Cache.

Step 6: Tap on Clear Data (this will clear your call log).

Step 7: Go back to Settings.

Step 8: Go to Date and Time.

Step 9: Change the format.

Performing these step should fix this error but if it doesn’t, you may have to factory reset your device.

Additional Method: On many of the devices, uninstalling Google+ app or its updates fix the issue. If Google+ came pre-installed then you have to uninstall the updates and disable auto update for the Play Store app. You can also disable the Google+ app entirely.
