I had noticed that July 2018 update cause some issues in IIS and this can be one of those issues.
For testing purpose, you can try to remove this update and check whether it solves the issue or not.
After July 2018 update, some other updates were launched by Microsoft as a solution for some issues caused by this update.
You can try to install those later updates to check whether it helps you to solve the issue or not.
If that not solve your issue then temporary try to remove July 2018 update and wait for the new update to launch.
It is possible that installing the new update helps you to solve your issue.
