Why does Dolphin Emulator randomly freeze?

for some reason, when I was playing Dolphin 5.0, my game (Super Mario Galaxy 2 but this happens with all games) randomly freezes. I don’t know what happened and there were no answers for how to fix this on the web (and yes I know I should upgrade to the dev versions but they are super buggy and unstable so yeah). Can someone help me please :-)?
