Send to Unreal - Static mesh with sockets crashes engine

[badVibes--]

• Addon: Send to Unreal
• Steps to Reproduce the Problem:
  1. Make a static mesh with a socket and send to unreal (I named the socket SOCKET_S0)
  2. Save the imported mesh in Unreal and shut it down
  3. Open Unreal again and try to open the mesh file (this makes Unreal crash)

This crash does not happen if I manually export and import the FBX.

• Error Log: No crash info besides Critical error message
• OS: windows10
• Addon Version: Send to Unreal 2.0.2
• Blender Version: Blender 3.10
• Unreal Version: Unreal 4.27.1

@badVibes I am able to reproduce this in UE 5.0.0 as well here is the crash log. Doesn't seem to be anything with the naming of the socket, since adding the socket with the editor is fine while adding the socket with the python API is not test01.log .

Here is the python that creates the socket. https://github.com/EpicGames/BlenderTools/blob/401d56571435e3c97ce1821353022a2327bab1ec/send2ue/dependencies/unreal.py#L796

In the end of the crash log there is something about creating the static mesh python glue before the crash. This seems more like an editor python bug. Ill create a report and close this out once I do.
