Hey no problem, I definitely appreciate the time and effort on your part!
Yes my other projects open fine, as well as a blank project. It’s just this particular one. I have copied the project on this problematic machine back to the PC that works, and it opens fine.
So basically you’re right- That there’s something inconsistent in this particular project. I tested it on a brand new installation of UE4 on my laptop and it doesn’t open there as well.
If I roll back and checkout a previous branch before the commit with the UMG/UI implementation was created, then it opens fine. So I’m guessing something within that is cuasing it… but not sure. Was hoping logs or something could be more precise in pinpointing it.
