Track all changes made in my magento community V2.3

I recently had a reindex done for my magento V2.3 community, after this I stopped getting any sales. I usually get 2/3 per day. After 10 days I have now had 2 sales.I later noticed that one of my biggest selling items was showing out of stock, however I had this item set to not manage stock.Is there a way to track all changes that were made and by who.
