My packaged game crashes when I use 'Open level by name node'.

GarboJunkie · April 17, 2023, 2:50am

When I play my game in the editor or standalone game it runs fine and the open level node works as expected. The player enters the main menu, hits the play button and then when they progress to the next level it works fine. However, when I package my game and load the player into the game the same way, the game gives me a fatal error when I load the player into the next level.

This is the blueprint that loads the next level. I thought that the event tick that runs to check for players in the zombie class might be an issue when loading the next level to I decided to destroy the actors before loading first. This did not fix the issue.

In the callstack inside the CrashContext/runtime-xml I found this:

Why is my game crashing in the packaged game but not in the editor or standalone?

ClockworkOcean · April 17, 2023, 6:09am

A couple of wild stabs in the dark:

Make the level name shorter
Use the whole path to the level /Game/…

GarboJunkie · April 17, 2023, 2:45pm

I tried using Open Level (By Object Reference) and faced the same issue.

Is there a character limit for level names?

GarboJunkie · April 17, 2023, 5:21pm

Here is the output log just before the crash.

ClockworkOcean · April 17, 2023, 6:04pm

Probably, and it’s much bigger than that. Just a couple of wild guesses, really.

ClockworkOcean · April 17, 2023, 6:08pm

Interesting that the critical part is about audio. Can’t imagine how that has anything to do with anything…

It could just be overwhelmed in some way, and that’s a random part that breaks. But…

I would try running the game in editor with the console open. Take a look at warnings and errors you get during the run. That could well point you in the right direction.

Packaged is more strict that editor.

GarboJunkie · April 17, 2023, 6:18pm

Ill do that now. Ill reply to you if I find something and dont know what to do about it. Thank you for helping me.

ClockworkOcean · April 17, 2023, 6:19pm

No worries. I know these post build errors are a pain…

GarboJunkie · April 18, 2023, 1:47am

I tried what you suggested but the audio fatal error when loading a new level still occurs.

Bump - Still need help with this issue.

ClockworkOcean · April 18, 2023, 7:46am

No idea, sorry. Did you get any console errors in the editor?

3dRaven · April 18, 2023, 8:01am

There was a similar thread on reddit where a worker thread crashed on prioritysoundmix.
One of the redditors mentioned to close all sound before “level transport”. (seemed a bit broken English).

If the audio is threaded & running then this might be the problem causing the crash.

Before the level travel try calling:
“Clear sound mix modifiers”, “Clear Sound Mix class override” and stopping non essential sounds and see if the problem persists.

in c++ you can close all audio via

  FAudioDevice* Device = AudioComponent->GetAudioDevice();
   if(Device != nullptr)
   {
   	Device->StopAllSounds(true);
   }

GarboJunkie · April 18, 2023, 2:06pm

What would the BP equivalent be?

3dRaven · April 18, 2023, 3:16pm

Not sure if it’s possible in pure blueprints but a sound class mix might be enough to do the work behind the scenes. It does hook into the equalizer mixer, that seems to be a problem as it’s the threaded part that is blocking the travel.

So in theory it might help if you use a muted profile. Or you could try clearing the asset keeping it empty. Experimentation is required.

A tutorial on how to use it

GarboJunkie · April 19, 2023, 3:33am

It worked. The solution was to use the following nodes in my BP before level load.

GarboJunkie · April 19, 2023, 3:37am

Lol now when I opened up a widget in the loaded level it gives me a different fatal error.

Seems like you might be trying to access a pointer to an unitialized widget. Its either missing in the package or its still a nullptr.

So checking if its valid should work.

You can also try to force adding spawned widgets at runtime to the packaging process.
