Secret Management error after 1.5.13 upgrade

I just updated to 1.5.13 on my test box, and every one of my dashboards is getting the error below. I even tried just the simple UDTypography and Button that is added when you create a new dashboard, and it too is receiving this error:

I checked the change log for anything script breaking from .12 to the latest release, but nothing jumped out at me. Is there some mandatory setting we now have to configure?

Product: PowerShell Universal
Version: 1.5.13

This is likely due to the file being blocked.

Run the following on your install dir:

dir -recurse | Unblock-File 

You may need to restart Universal.

Hi, Adam. I did run that as part of my update script, but I will try again.

Ok. You can always verify it worked by right clicking and viewing the file properties.
