You’re trying to read from an empty array 
@ClockworkOcean
There is no function in the callstack created by OP. If it was, one of those symbols would have a meaningful name and it would come from his project’s dll. So he is NOT the one trying to read from and empty array. It’s an issue with the Engine/Editor
@ArkCreator
Did you write any actual C++ code or is your project blueprint-only?
Do you know what causes this issue (reproduction steps)?
If it’s an issue caused by a faulty blueprint node, you may find a blueprint backtrace in the log, right before this whole message appears…
…and there might be some useful warnings/errors in the log besides the callstack.
You can copy-paste WHOLE log here, if you don’t know what to look for.
The callstack alone does not tell anything useful because you don’t have debug symbols (that’s why it says UnknownFunction everywhere).
The error Assertion failed: (Index >= 0) & (Index < ArrayNum) is meaningless because we don’t know what have led to it happening. We need more context.
here’s the full log!
Tournament.log (1.1 MB)
I have no idea where that is it started happening after I changed my engine version and updated a plugin I believe
This crash happens during shader compilation while packaging the project, right?
Did you make sure to delete all intermediate files from your project while changing the Engine version?
If there are any build artifacts from older versions of engines they can cause all kinds of issues.
Try deleting those files and then rebuilding/repacking whole project.
Here’s the list of all intermediate files: Cleaning Your Project | Unreal Engine Community Wiki
If this does not help, provide a new log.
Crash occurs right after this error:
[2024.09.19-07.07.01:636][582]UATHelper: Cooking (Windows): LogTexture: Error: Unable to get texture source data for synchronous build of /Game/Meshes/Terminal/Terminal_Fridge_UV_Computer_2_BaseColor.Terminal_Fridge_UV_Computer_2_BaseColor
[2024.09.19-07.07.01:643][583]PackagingResults: Error: Unable to get texture source data for synchronous build of /Game/Meshes/Terminal/Terminal_Fridge_UV_Computer_2_BaseColor.Terminal_Fridge_UV_Computer_2_BaseColor
…so we can speculate that asset /Game/Meshes/Terminal/Terminal_Fridge_UV_Computer_2_BaseColor.Terminal_Fridge_UV_Computer_2_BaseColor might be broken.
but before doing anything with said asset try approach with deleting intermediate files first
Ok I did what you said and now I no longer get that error and my game cooks! however, now I get a bunch of warnings when I try to package it and the packaging ultimately fails.
NEW LOG
Tournament.log (5.8 MB)
Log is super huge and has lots of warnings and errors.
You should fix them yourself one by one. It is impossible to recognize them all by me.
Most of those errors are about broken blueprint nodes.
Are you sure all blueprints are compiling in the Editor?
When you Play In Editor aren’t you getting any runtime errors?
Anyway, crash is solved which was the initial problem, so this thread can be closed.
If you won’t be able to solve the errors you should probably create another forum thread.
