Sims 2 Legacy crash with no error code again

Hello,

I am experiencing an issue with The Sims 2 Legacy Collection on EA App.

The game runs normally until I try to load certain lots. During the lot loading screen, the game suddenly closes and returns directly to the Windows desktop without displaying any error message.

The issue is not related to a single lot. It happens with multiple different lots in my save game.

I have already performed several tests.

I launched the game only through the official Legacy Collection executable.

I tested without suspected custom content by removing some CC-related files and folders.

I cleared the game cache files.

I tested the game in windowed mode.

I repaired and verified the game files through EA App.

Additional information:

No Exception_.txt or ObjectError_.txt files are generated after the crash.

The game logs show a graphics-related error:

D3DError: Bad return code : D3DERR_INVALIDCALL

in GZGraphic4ShaderProgramDX.cpp.

This behavior seems more consistent with a graphics engine, DirectX, or shader-related crash in The Sims 2 Legacy Collection rather than a typical Sims 2 object error, custom content conflict, or gameplay issue.
