suggestd quit unexpectedly Help!!

iMac 2012, macOS 10.13.3

Help!

only while using Safari, repeated multiple messages, every few seconds, as title of this message.I have no Safari Extensions and it happens even when I am not running any other apps. It does not happen in Guest Mode, only in my usual account.

I am not an expert, but after reading old threads on here I have looked at Console User Reports. They all look much the same and relate to /System/Library/Assets/com_apple_MobileAsset_CoreSuggestions/a5cf95a5befdb91b8b b6f307af9250f1c8adff93.asset/AssetData/CompiledPatterns.plist

Here is an example

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not read pattern plist from /System/Library/Assets/com_apple_MobileAsset_CoreSuggestions/a5cf95a5befdb91b8b b6f307af9250f1c8adff93.asset/AssetData/CompiledPatterns.plist: Error Domain=NSCocoaErrorDomain Code=257 "The file “CompiledPatterns.plist” couldn’t be opened because you don’t have permission to view it."
