While working on my project, I happened to encounter an issue whenever I change the CollisionFidelity of a MeshPart and try to parent it to an object afterwards. Studio proceeds to crash and not respond indefinitely (I hopped off my PC and left the frozen Studio instance for around 20 minutes, after which I came back to absolutely no changes).
Relevant FFlags enabled: CSG v4 related flags, including Mesh Union support, although no union operations are running, so I doubt this is a concern.
Expected behavior
Studio does not crash while editing the collision properties of a MeshPart and parenting it afterwards.
Can you provide logs when this happens? It’ll help narrow it down.
There are absolutely ZERO crash reports being logged for some reason. I’ve looked everywhere and the logs are just gone.
Nevermind… I found a memory dump. Is it OK for me to share this? I’ve heard about user information just being leaked in them.
There’s no crash report because it’s a hang and not a crash, don’t look in there. Look in your normal logs folder instead, and find the most recent.
A memory dump is useful in theory (though yes, never post them publicly), but only if you’re confident it’s actually correlated with the hang–I suspect because it’s “just” a hang, a memory dump isn’t actually being made, and you’re looking at one made earlier.
I… don’t think the crash is even related to MeshParts in any way.
Take a look at this. If you deem this an actual bug that requires a new topic to be open, let me know.

An ANR randomly just starts and I don’t know what’s happening.

Can you PM me the memory dump if you have it? And also see if this bug happens when you disable plugins?
