Migrated SSRS Server will not load reports - sql-server

Question

I started this process back in November with this question: How to migrate an existing SSRS setup to a new server?
I was able to migrate everything to the new server without any issues. There were no errors on any of the tabs in the Report Server Configuration Manager. And the Reporting Service started with out errors. I was able navigate the expected "directory" structure through the web interface. However, when I tried to execute a report, upload a report or manage the report I received an error dialog that read "An error has occurred. Something went wrong. Please try again later." This isn't the most helpful error, so I went to the Report Service error log and found this exception in the log:

I spent a few hours looking this error up with no solution. It could be that I was pretty fried and I missed something, but any guidance would be appreciated.

You may find its faster to create a SSRS project in SSDT, import the reports and redeploy them. You may have to recreate the data sources but in my experience this is the fastest way to get it done.
