Could not load folder contents - SSRS Report Manager

When I tried to access the report manager after a fresh installation of Sql Server Reporting Serivces 2016 using the url http://localhost/Reports , I received the below error.

By default the installation gives access to Builtin\Administrators. In order to resolve this error below are the steps that you can follow.
Step 1 Run internet explorer as Administrator and open the Report Manager URL http://localhost/Reports



Step 2 Click on Site Settings icon and then click on Security as shown.  You can see only one assignment of roles here for Builtin\Administrators

Step 3 Click on Add group or user assign the role assignment as shown below. 



Re-open internet explorer (non-admin) and recheck the url. You will not get the error anymore.
