UE5.5 iOS Cook Error.

[1scriptz]

Been building out a new ios game on windows for a few days and decided to move it over to Mac for testing/pushing to ios. Running into a plethora of errors but this one was reproducible in a fresh project.

I've not tested this with other platforms android/mac but I do notice this reproducible error on iOS cooks.

Steps:

1. Create a fresh ue 5.5 topdown project
2. Enable Darker nodes
3. cook the project for ios

`LogMac: === Critical error: === SIGSEGV: invalid attempt to access memory at address 0x3

LogExit: Executing StaticShutdownAfterError`

To Fix: Have to disable DarkerNodes for cook to succeed.

Hope it helps and let me know if there's anything else I can provide.

That's pretty weird... Darker Nodes configuration file explicitly tells Unreal Engine that it's an editor plugin, and that it shouldn't be used during build.

Could you please tell me if you're building the game directly from the editor, or from a command line?

[hugoattal]

Do you happen to have Electronic Nodes too? Does it also trigger this error? (If you don't have it, don't worry)

[1scriptz]

There is another scenario I didn't test: removing the Fab plugin. I do know that causes other issues. I realized this just now.

And yes, I had Darker nodes, Electronic Nodes and Fab installed.

All done in the Editor, nothing command line.

Hum, since it seems to have something to do with the UpdatePopup, and there's a bug with it right now, I suggest retrying once it's fixed => https://github.com/hugoattal/DarkerNodes/issues/194
