### Describe the bug

In Amplify Console I am unable to add user to a group. As soon as I take user email input in focus, the page becomes all white. By inspecting it I can see the message that JavaScript should be enables for app to work, but it is enabled (otherwise how it would work before)

### Expected behavior

List of registered user mails should popup when focus on input field

### Reproduction steps

1. Navigate to user management
2. Go to groups
3. Select a group
4. Click on add user
5. Form pops up with a single input to insert user mail
6. Focus the input field
7. Page becomes all white

### Additional information

The issue is only present when trying to add user starting from the group. In other words user can add itself to a group, but the group cannot add users. So it must be some frontend related bug I guess.

Start in Amplify Console's user management flow, then open Groups, select a group, choose Add user, and focus the email input to reproduce the blank page. Inspect the browser console and the frontend path responsible for this dialog; done means the registered user emails appear and the page remains usable when adding a user from a group.
