I have built an iOS keyboard extension, before it is installed the system prefered language is "English" like so:

After installing the keyboard extension the system language is set to "Corsican", like so:

Corsican is being set because the bundle identifiers start with co. which maps to the ISO 639-1 language code for Corsican co. I've verified that my PrimaryLanguage is en-US, see below a section of Info.Plist. I've verified the bundle ID is the root cause by changing the bundle ID to something not starting with co and this behaviour disappears.

This seems like a bug in iOS. Any suggestions what to try?

It is a critical bug in iOS which has no workaround and seriously affects users... yet it's still not fixed even though first reports appeared 6 YEARS ago!
