Can't Select/View Mobile or Wi-Fi Data usage - "Settings has stopped"

[EnzoS]

Since our recent OTA Oreo 8.1 update we haven't been able to select or view either mobile data or wi-fi data usage on our Samsung Galaxy J7 (Verizon). Path: settings/connections/data usage/mobile data usage (or wi-fi data usage).

When selected, either mobile data usage or wi-fi data usage is displayed for a fraction of a second then is immediately covered by a pop-up window saying "Settings has stopped. Open app again."

We have so far tried clearing caches locally and wiping cache partition with no luck. We've also read a variety of recommendations (online) to "clear data" for some apps. One in particular that got our attention was the "settings" app. We haven't read anywhere that doing a "clear data" on the setting app will cure the issue where data usage can't be accessed.

Is it safe to "clear data" on the settings app? I know doing so will return the "about phone" developer options to a "stock" appearance but what else might happen or what else might be lost (and require re-installation or re-configuring) following deletion of the settings app data?

You'll most probably loss a ship load of setting I would think, as in go back to default, (wifi password, bluetooth name, sound profile, display setting, secuity setting) but I haven't needed to try and hope I never do.

Thanks for your comments. I knew there would be some settings/configurations that would have to be inputted again and I'm just about ready to pull the trigger. I'm hoping to find a posting somewhere that lists all of the settings that would be affected...unless of course, you're sure all that you listed would be the only ones affected???

I appreciate your comments and hope you might have something else to add.
