Why my available languages disappeared?

Hello everyone;

I have (Samsung j7 pro - android 9), I lost all languages in available languages section after I did reset it before and I tried to (update) it and (keyboard reset) again even I did (factory data reset) but it's not back.

There's no option to download / updating from "3 dots" choice.

How can I get my all languages in available languages section back?

PS.: Available languages was containing (Thai, Hebrew, Indonesian, Malayu and etc) and ready to download.

Thanks;
