Safari not responsive on IMAC

[themm20]

Hi- - Have a 27" IMAC 2019, 8 GB Memory, OS is Mojave 10.14.6- upgraded from previous IMAC, only using for ~3 months & suddenly can't seem to load any webpage from Safari 13.1. Checked for updates, cleared history, clicked "Develop" & emptied caches, disabled extensions & still no luck

. My new windows open with"Favorites" page which were usually full color Icons but now are "grayed' out if that means anything? Safari doesn't work on wifes user account either.

Been using Chrome to access the internet & that seems to work fine.

Thanks for any input on how to solve this!

Follow up: I was advised by Apple Support to reinstall the OS which solved the problem. (Turned on power button, then immediately held "command" & " R" keys until the progress bar was about 3/4 full. Then just clicked "Reinstall MacOS" from the menu that appeared. Took about 45 minutes- Hope this helps!
