Fortnite keeps crashing on switch?

Whenever I play for a while sometimes the game crashes after 1.5 hours… It says that this application was closed due to an error… What can be a problem? When I'm not using my switch, I do not switch it to standby but completely… I don't know what to do anymore and am afraid that I will no longer be able to play the game…

Maybe your internet is not good enough or your switch is not up to date

So can it be that Wi-Fi is bad that it crashes because of that? Hoffe I hope so… So it's up to date

Ne is not the Wi-Fi have the same problem and many others
