Site started showing .net core error page suddenly

Hi,
We migrated our site to .net core about 10 days ago. Today suddenly our site was down and showing a .net core error page. Immediately, I restarted the app pool which fix the issue. I cannot remember the error properly but it was .net core white colored error page with one line. I also didn't find anything in nopcommerce error log which may be the reason for this site down. Nothing was deployed at that time or no new plugin was installed during that time. In .net core log the last couple of line before site going down are as follows

      Executed action Nop.Web.Controllers.HomeController.Index (Nop.Web) in 303.9616ms

Anyone have any idea what might be the reason for this error?

Could you check "Feed.FrooglePlus" ?

And also Themes/Venture/Views/Catalog/CategoryTemplate.ProductsInGridOrLines.cshtml file
