raspi-config cannot set wifi country on RPi4

[Bosse_B]

I have an RPi4B with 2GB RAM and the Raspbian Buster system.
When trying to set the WiFi country via sudo raspi-config (localization/change wifi country) I always get an error message:

Could not communicate with wpa_supplicant

and

There was an error running option I4 Change Wi-fi Country

What can I do to fix this?
(I am trying to set up my RPi as a WiFi AP).

Use the documentation provided by Raspberry Pi instead: it doesn't require using raspi-config.

Works for me. How can I reproduce this?

I already used this method and it did not work. Wound up with an AP SSID showing up for 3 seconds then disappearing for 20-50 seconds and then reappearing again ad infinum.
So I reverted that attempt.
But that question about the AP belongs to my other thread rather than this simple thread about raspi-config, which is a basic question about something that should work on RPi unless the switch to Buster has broken it...
