Apps want open

I have a macOS Catalina My MAC will open but my apps want. The finder, photos will open with no problem. When I open Safari, googles etc they will open, but when I enter a web site it will not open the site. When I open the App Store, maps, mail etc, they’re completely black. I did hit option command and esc to force quit the apps that were open and shut down my Mac I did it a couple of times. It did not work. Need help. Penny
