Import dwg in Maya 2025.3 causes crash on saving file

[a.mayaUser]

Hi everybody,

a client gave me a dwg (2d) so I can build the 3D file from that.

Problem is, after importing the file in Maya 2025.3, any attempt to save the file will cause Maya to crash like this:

Date/Time: 2024-11-20 10:33:06 +01:00
Application: maya.exe
Error: Access violation - code c0000005 (first/second chance not available)
Crashed Module Name: OpenMaya.dll
Exception Address: 0x00007ffd3f763280
Exception Code: c0000005
Exception Flags: 0
Exception Parameters: 0, 74786575be

This does not happens in Maya 2024.2, so it must be something wrong happening in 2025. Also I noticed that the viewport is suspiciously slower when panning the imported dwg as curves, while in 2024 is noticeably faster.

It looks like a bug, has anyone encountered this problem?
