IDB Stream stops when changing device's language #879

Starting companion with below command:

idb_companion --udid <udid> --grpc-port <port> --terminate-offline TRUE

and idb stream with below command:

idb --companion 127.0.0.1:<port> video-stream --udid <udid> --fps 10 --format minicap

this starts fine, there is unreadable data in video stream output, and "Send frame of video_stream" logs continuously coming in companion command output.

but as soon as I go to Settings > General > Language & Region in the iOS Device, and change the language from there, streaming and companion logs are paused.

any idea why is it happening, is it expected behaviour or any way language change can be determined from code?
