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

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:

1.

2.

3.

 

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.

 

2022.2.10f1

 

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

We are getting this one too. Unity 2022.3.15f1

 

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.
