UiDemo app wont open after entering credentials

After typing in the username and password in the app and click log in, it just closes down and nothing more happends. Even trying it manually wont work.
Any one else experienced this issue?

Hi @axel.canneroth

There may be an error occurring within the application or on the system level that is causing it to close down after the login attempt. Check for any error messages or logs that could provide insights into the issue.
