Why does my unity stopped working when using it offline?

i don’t have internet at home so i use unity offline but when i try to test the game it crashes but when i am connected to the internet (When i go to my grandpas place) it won’t crash like is there a way to test my games offline without crashing it?

It probably depends on if your game is using any online services. If yes, then you could maybe surround the calls with try-catch blocks to catch and handle the exceptions. In this way it won’t probably still not run completely same like when you have internet, but at least you could play it without crashes…
