I try and play my game to test it out and I get this error message: -

Any idea why??
I've been able to play it before and it worked fine!!
The room has its after fadein event linked to a function, but you've since removed it from the room's script.
It's right there in the message: error (no such function in script) trying to run room_AfterFadeIn.
In other words, you need to remove missing function name from the room's events panel.
