I thought this forum to be most fitting for this question.

Basically, I can't build my game. It throws this error every time:

It only happens with my main scene, which is fairly big, so I initially assumed it was too big, but even deleting most of the assets for testing purposes didn't help.

In the Unity forum they said it was an issue with the beta and it would be resolved when the new version comes out (2018.1 if I remember correctly).

But I don't really have the time and wondered if there isn't possibly any solution to this.

It happened previously with another version of Unity. I resolved it by saving the file directly to a flash drive, since apparently Unity wanted to write over some files it was currently using, unless you switched hard drive.

Now it appeared again and I'm at a loss. I'd be thankful for some help

It isn't. Game Design isn't for technical questions. Moving to a more fitting forum.
