there is an issue that came in the highlight which is related to Magento. I am attaching the issue.
It is related to the products data. The price of products is not getting indexed with Magento indexer.
Website was running ok but, as there was no products prices no products was visible.
It can be possible due to many reasons. Check your database or some server-side issues or anything else. To catch the exact issue I need to look deep into your website. But first, you can check the basics.
Hope this will help you.
Click KUDOS and accept as a solution.
Maybe you have created a new stock and haven't assigned the source to the product.
