Safari is not working!

Hello everyone,

I had this problem after i updated my OS to the latest OS which is macOS Catalina (10.15.7), and when the update finished i lunched safari and there was nothing!

i looked it up every where but it didn't fix it... what is happening is this:

when i click on safari app to lunch it nothing shows up but the little dot indicator under safari that indicate the app is working is on, and it show the menu bar also in the top and i can click to show the menus like file, edit, view, etc..., but not working, for example if i want to access preferences from the safari menu (i click on the safari preferences) but nothing happens.

I've almost tried everything...(cleaning, removing cache, booting up in safe mode, reseting PRAM/NVRAM, using the disk utility to first aid the disks, reinstalling macOS....) but nothing worked yet

so i will be thankful if anyone can help.

thanks a lot.
