I downloaded 26.0.1 to use it in conjunction with Inventor (FDU).
However, an error occurred while attempting to use the backgrounds button to overlay an AutoCAD file, as shown below.
When I select a path to load an AutoCAD dwg file, the program freezes immediately and then terminates.

It worked as intended before I downloaded AdskInterop 26.0.1.
Even after deleting AdskInterop 26.0.1 and downloading AdskInterop 26.0.0, the program terminates in the same way.
Suspecting that the complexity of the dwg file might be the issue, I tried loading a very simple layout (just a rectangle) as a test, but the program still terminates in the same manner.

Below are the versions of the programs currently in use:
Intentor 2026
FDU 2026
AutoCAD Mechanical 2026
Navisworks 2026
How can I use the underlay feature?
