I installed Microsoft Apps like Recruiting Helper and project Management.

The App Installs correctly but when I open it, I get the following error:

Sorry, we couldn't load this app.

We weren't able to load the app's home page. Please let your administrator know about this.

Searching the Logs for Errors with that Correlation ID, I found:
