It doens't show the complete error details yet, still can you try below manual workaround once -
1. For each user logged into the machine, close all the Visual Studio instances.
2. Wait to make sure that the IIS Express is stopped. The IIS Express should be automatically closed shortly after Visual Studio closes (sometimes it could take couple minutes). Two ways to verify IIS Express is closed.
* When IIS Express is running, there is an icon shown on Windows icon try at the right bottom corner of the desktop. When IIS Express closes, the icon should disappear.

* Open the Windows Task Manager, there is NO “IIS Express Worker Process” in the Processes tab, or “iisexpress.exe” in the Details tab.
3. Open the windows command line window, and type in the below command to restart the SSRS reporting service.
net stop reportserver && net start reportserver
4. Open a browser (any machine) and go to the Dynamics 365 Finance & Operations, and run a report.
If it doesn't help, then probably you will need to apply a binary fixes from MS.
