Thank you for reporting this issue. I’ve confirmed that Blender crashes when using the Add Convex Hull modifier with the Use Loose Island option enabled on this particular asset.
Workaround:
While I investigate the root cause, you can achieve the same result manually:

• Enter Edit Mode.
• Select the entire mesh.
• Press P > Separate by Loose Parts.
• Apply the collider creation to each of the resulting objects.

This method should work as expected and provides the same outcome as the Use Loose Island option.
Next Steps:
I’ll prioritize this bug based on how frequently it occurs and its impact on your workflow. Could you let me know:

1. How often you encounter this issue?
2. How much it affects your current project?

Your feedback will help me address this more effectively. Thanks again for bringing this to my attention—I’ll keep you updated on progress.

Crash also appears when using other primitive types like box or sphere. So it's connected to the use loose island function.

Unfortunately, the same doesn't work.
