Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)

We have SharePoint 2013 Servers that were patched with windows updates and since then we are receiving the following error. We have restarted the servers, removed the windows updates manually and then restarted the servers, restored to a copy of windows server before the windows update but the error is persisting. We have also removed the temporary files from Windows directory and nothing is helping.

I have attached a screenshot of the Windows Updates that were applied to our servers overnightenter image description here

I ran into the same exception when developing on Sitecore, and an iisreset cleared the issue.

The solution appears to be:

Create a new registry DWORD value called LoaderOptimization and give it the value 1 within the key “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework”.

I was able to solve this issue by going into Bindings -> Edit, then removing "localhost" as the Host Name of the site. Worked after that.

Try disable "Remote Desktop" if it is enabled (example)

After running the command isreset and changing registry,my problem solved.
