Cannot create power bi apps

Seems like could not reproduce it in my side as far as my test in Power BI Service.

You can try to create a new template app workspace and republish this report to this workspace to create an app to check this issue again.

See: Create a template app in Power BI 

If this issue still happens, you can try to open F12 to find some information on the Console pane.

I actually experience the same error - creating a new template workspace also did not help.

F12 Console showed the following error:
