Unable to Start Recorder [SOLVED]

After the update from yesterday (2021-08-16T05:00:00Z) I can no longer start the web recorder for both new tests and for existing tests. You can still open existing tests to modify; When you hit the record button, the “System Under Test” would open as expected however, you will not get the recorder window. All the UI elements are also unclickable as well. In the DevConsole I am seeing a lot of unchecked runtime.lastError: Could not establish connection. Receiving end does not exist. errors
