When I try to open my project, it closes after loading about 71% of the way. There’s no crash report, it just closes. I searched around for a bit and found that my answer probably lies in the Saved/Logs folder. I took a peak in the most recent log and was met with a rather confusing log, as expected.
I tried the obvious solution of verifying my version of the engine, but got the same result with an identical log. I tried opening other 4.11 projects and they all work fine.
Here’s the log. The last lines about a missing Slate file are present in logs of other working projects, so I’m not really sure what to look for here.
Are you using any plugins? There was an issue regarding the Substance plugin. If you are using this, go ahead and remove it from the Engine installation directory Epic Games->4.11->Engine->Plugins and remove the Substance files.
If this is not the case, try opening the project up in the 4.12 Preview to see if you are still experiencing the same error.
I finally got around to trying to fix this. A somewhat long chain of events led me to realize I never tried running the debugger. I did that and got pointed right to a recently-added line of code that I have commented out. I’ll try to figure out what’s wrong when it’s not 2 AM.
