diagnostics code?

[Gary02468]

When I dial the USSD code *#0*# in my unlocked US S22 Ultra, it starts by properly saying "USSD code running...", but then says "Unable to process this request". Do others find the same thing? Is there a different code to use, or a way to make the standard code work?
