When packaging my build, it works perfectly fine in the development config. However, when in the shipping config, it crashes due to a fatal error. I know the plugin causing it is the EOS Integration Kit, its not something I can keep off for obvious reasons. I didn’t purchase it, but built it myself through their GitHub. I’m in UE 5.5. Any ideas? Do I just need to try re-building the plugin?
I’ll just say that we were running into the same problem, and it was such a show-stopper for us that I had to tear the plugin out and build a replacement interface up from scratch for our use-case :\ so you’re not alone, but the fix was ugly for us.
After reaching out to the devs of the plugin and building UE from source (just so I could get shipping logs, how silly is that?) the solution for me was this:
Go to Plugins > Turn off “EOSShared” > Restart project.
That’s it. It will prompt you to turn off a whole load of other things, if I remember correctly. Even the fab plugin had to be turned off because it required EOSShared to work. Turns out any other EOS system doesn’t get along nicely with the integration kit
Solution was found! I think it seems it might be too late, but if you want to potentially go back and use the EIK plugin, this should work. I’d make a test project just to see if it still crashes first though, in case there are other issues
