Blank App page with Window Authentication

Product: PowerShell Universal
Version: 5.6.7

I am having a similar issue to these old threads

Set up windows authentication, added the group claim to the admin role. I can see the claim passing correctly and I am getting the correct role when looking at My Identity

But when viewing an app that is set to only the admin role I get a completely blank page

If I log in with the default local admin account the page loads fine.

Looks like this popped up before here as well. I tried clearing the cached claims and restarting the service and I still get the same issue

This was figured out on the Git issue. The problem is that my username was coming in as all uppercase, but was being saved as all lower case under identities. Manually modify the username to match uppercase and that fixed the issue.
