WOOCommerce categories not showing products

Dear support

https://www.istore-ksa.com/

I run this store using WOOCommerce latest version and since I updated to the last version suddenly categories stopped showing products at all,

Mean once you click on any product category it will show empty page, it’s a known issue and I tried lots of solution but none worked and its seems WOOCommerce support tickets are stopped until 22 Sep.

Your kind support please into this matter.
