is there anyway to get the modified version of metis used by UE5 , the windows version

[geo3data]

I tried the official metis version compiled to the windows UE, but UE5 crashed of GKLib memory release, so I wander what UE5 modified, and according to its linux version, UE5 used official metis in linux, this confused me,

UE5 is source-available, so you can check the source directly. Last I checked (quite a while ago) I think it was using an unmodified version.

That being said, there are quite a few well-formed graphs that Metis will crash on. If you are able to share the inputs that cause the crash, that would be helpful (I don't know of a builtin way to do that in UE5, so you'll have to attach a debugger).
