Crash when the plugin is enabled in UE 5.4 packaged builds

[StefanLundmark]

My packaged Unreal project crashes on startup when the plugin is enabled.

This is the callstack of the crash:

Things I've tried:

• Verified that steam_api64.dll is included in the package.
• Rebuild.
• Wiped DerivedDataCache and Intermediate folders followed by Rebuild.
• Build on a separate computer.
• Checked to make sure all plugin dependencies are included, like SteamSockets and the OnlineSubsystems.

It seems the top call in the callstack points at some kind of dynamic library not being found?

I'm not sure what else to do. I'm on the latest version of the plugin from GitHub.

Yeah some people have this issue where it doesn't bind to the DLLs, however its using the engines implementation not something custom of mine and it works for the vast majority of users. I've never been able to reproduce it on any of my systems to track down what the engine structure is doing here or if its a weird load time issue.

I have considered just ripping out that event binding all together.

[StefanLundmark]

I understand. Well, not much you can do if you can't reproduce it reliably.

Thanks for confirming, Joshua!

I moved steam_api64.dll from its ThirdParty location in the packaged game, to where the game executable is. And now everything works. I don't understand but maybe this will help someone.
