HTTP Error 500.30 - ASP.NET Core app failed to start on working web site

Question

web site works normally, but about once a day it throws error and stopped working with error HTTP Error 500.30 - ASP.NET Core app failed to start, event log says Access to the path 'C:\inetpub\wwwroot\mysite.com\Plugins\bin\Plugin.plugin.dll' is denied. But there is access to that path. I tried to remove plugin, but same error happens on different plugin folder.

I tried different solutions from stackoverflow, but still no success.

It starts to work when recycle a pool, I have set up it recycling for once a day, but it happens not as recycling pool schedule time.

Apprecite any help.
