I found one more clue, it only happens over 26.3. Customer inquiries keep coming in. We don't even have a proper guide, so please solve it quickly.

I also get same error only for certain users.

and when i add AppShortcuts.xcstrings and remove AppShortcuts.strings, below error is occured "AppShortcuts.xcstrings is only supported for iOS 17.0 and above. Use AppShortcuts.strings for previous versions." when i add both AppShortcuts.xcstrings and AppShortcuts.strings, below error is occured "AppShortcuts.xcstrings cannot co-exist with other .strings or .stringsdict tables with the same name."

is there any guide or sample code about AppShorcuts.xcstrings? i don't know how to set key value when string has (.applicationName). ex) "open (.applicationName)"
