@GSGBen - Sorry for not following up.
We had a couple different findings
First, make sure to Unblock-Files is extracting from the zip: Unable to Start Dashboard - 1.2.2 IIS
Second, make sure that if you have WebDav Publishing enabled on your machine it’s correctly configured to allow all verbs: Cannot remove or edit api's and identities after created
Finally, I would suggest that you have the latest version with the security fix from today: Security Bulletin – PowerShell Universal Role-Based Access Controls
If none of that applies and you still have this issue, let’s jump on a Zoom call and get this sorted.
