What should I talk about when I meet someone new?

:( i feel so weird when i stay quit and i don't want to talk about the usual topic (work and study ) because they seem to get bored immediately, there is this app that connects you in a voice call with random people, i use it sometimes and i don't know what to talk about i feel so lonely i moved recently to a country that i don't speak its language and I need company :( but i don't know how to approach people not on the internet or on real-life cz i am a shy person but i really want to change that, any advice?
