Hello. I’m trying to update my project from 4.7 to 5.1.1 (I’m trying an older version because I’ve heard it’s better). The editor converted my project, just had a compile error saying ‘IniKeyBlacklist’ is depreciated, so I fixed it. Then I tried to open my project, and Unreal Editor crashes with no error message whatsoever, just closes and goes back to Epic Launcher. I’m having a hard time trying to figure this out because there’s no error whatsoever and I don’t know where it could be a log I can look at. Any help is appreciated, thank you.
Additional info: I have a backup of my project that I still can open on 4.27, if that helps. My project is mostly on Blueprint, but there are some custom C++ classes.
Hello there @voltsm! Let’s see what we can do here.
Since your current project was on a previous version of Unreal, and its now updated to 5.1.1, all previous settings from the old build are most likely causing a conflict.
To clear you engine settings, delete yourproject/Config/DefaultEngine.ini. Then start an empty, new UE, and open your updated project. This should either recover your project, or crash again but return an error log.
Using said error log should allow us to pìnpoint the problem. For further details, please check this related thread:
Managed to get it to work but I had to delete the config folder BEFORE converting to 5.1.1.
