Unity crash on loading a scene (ParticleSystemParticles::array_reserve)

Unity Engine

Hi.

We’ve been experiencing a crash that appears on loading a new level. It is not 100%, but after some amount of loading it occurs (it could be 1 load, could be 5).

Looks like it somehow related to the particle systems every time.

In the .log file it simply outputs:

But sometimes it writes a stacktrace. Sometimes we can take a stacktrace from the crashdump file. Here are 3 different stacktraces, but all they have in common this line:

Here are some crash stacktraces:

PS: Our temporary solution is – we’re disabling all particles on all scenes and enable them manually after the scene is loaded. Magically, that solves the crashes.

what unity version?

2022.2.10f1

Are you able to submit a bug report, with a reproduction project?
We’ve not seen any other reports of this (yet)

6

No, sorry. That happens on our very big project and stripping it down to a minimal reproduction project will be too much work.

Also, the bug still reproduces on 2022.2.5, but with less chance (or we need to reload a level more times to get the crash). But it is still there, so that’s not something new for ver .10

Ok thanks for the info!

I think it might be fixed for me after duplicating the particle system that was causing the issue. Then deleting the original. Potentially a corrupt game object? Looking more into it now.
