Short description of error
Blender crashes when using particle system + grease pencil line art modifier

Exact steps for others to reproduce the error

creating a blank grease pencil object
applying a Line art modifier on it
source is a simple 3d model of a spaceship modeled in blender
creating a plane as a source of particle and simple retangle as the object being emited
when trying to play the particle system or bake it, it crashes every single time
if the grease pencil is hiden or deactivate, the particle system is functionning
same error occured on a different computer

I can't replicate the crash. Can you attach a minimal file that reproduces the issue?
Can you also attach the crash log created by Blender? https://docs.blender.org/manual/en/latest/troubleshooting/crash.html

Thank you for your answer
Here I recreate the issue with a simple scene that you'll find attached to this message, also there is no crash log created by blender, it just vanished without any error message :

Looks like crash was introduced somewhere between 118803893e - 6ee14c966d

Unable to reproduce on lite build so I don't think I can bisect
@OmarEmaraDev hi, can you bisect?

I probably should take a look at this.

This only happens sometimes on my machine, where it looks like it's the particle mesh has this mesh.runtime==NULL problem. I'll take a look to see if I could call a ensure somewhere before loading for instanced objects.

@ChengduLittleA Can someone from lineart decide on whether this is a bug or a known issue? @OmarEmaraDev if the bisect got anywhere, please share away.
