World won't download anymore -> returns to launcher

[Coastalranger212]

I've been playing with the hexical future 2.0 modpack and except for some random shutdowns it has worked fine. A couple of days ago it won't go past the downloading world screen and returns straight back to the launcher. How can I fix this? I already went to the forge file and changed the two line with removesomethingentities and tiles to true. Didn't work.

Why? WHY??? Why did you change the original file format of the log?
