Why does my Garageband crashes when I try to export a song?

Hello, I have an iPad 4, and it's still on the IOS 10.3.4, I'm using Garageband on it for a very long time, you can say for six years, but I have a problem now, it's when I try to export a song that I made, it keeps crashing and kicking me out, what should I do in this case?.. Ah and I don't think that I saved none of the songs on my icloud, but I just checked that the icloud is connected to my Garageband in the settings (it's on).. So what should I do to fix that?

And Thank you.
