Verified on Android 9 and 11. The problem is not reproducible anymore. The "Generate New Alias" button does not redirect to the error page and the alias is generated without problem, both with a premium subscription and without one.

This started happening again on Android 9, while on Android 11 works fine. What I have noticed now is that when the user is redirected to that page with only text on it, a new alias is created and the text displayed previously is related to the name of the freshly created alias. Observe "czeuj32vq" in the next couple of examples.
