"Downloading en-US"

Google Pixel 8a, Android 14

In the settings for the default Phone app, I clicked "Call Screen ".
That took me to a screen headed "Call Screen", as expected, but about
the top third of the screen is now taken up by a white window with an
orange bar containing the text "downloading en-US". The setting for
"Automatically screen calls" is grayed out, as are its sub-settings
"Maximum protection", "Medium protection", and "Basic protection".

It's been like that for an hour so far.

I assume it's downloading some sort of language pack, but should that
be taking so long? If not, any suggestions for troubleshooting?

(I did try googling, but the search terms I could think of didn't
lead anywhere useful.)
