My library can't display modded content, while gallery can

Additional testing and reproduction results

I have now been able to reproduce this issue with all mods completely removed.

I first suspected that MCCC or another mod might be involved because MCCC was reporting an error while processing a .householdbinary file. I renamed the affected file, but the game simply generated a new .householdbinary, and MCCC produced the same error again. This indicated that the individual file was not the underlying problem.

I then performed a clean test:

• Renamed my entire Mods folder so that no mods or custom content could load.
• Cleared the usual Sims 4 cache files, including the localsimtexturecache.
• Cleared both cache folders.
• Cleared the EA App global cache.
• Started the game again with no mods installed/loaded.
• Tested the My Library filter using Include Custom Content.

The result was the same: the game freezes and then closes when “Include Custom Content” is selected in My Library.

The Gallery behaves differently: its equivalent Custom Content filter continues to work normally.

Therefore, the problem can be reproduced without MCCC, without any other mods, and after completely clearing the relevant caches. This rules out my installed mods as the cause of the crash.

The fact that the Gallery filter works while the identical type of filter in My Library causes the game to freeze and close appears to point specifically to the handling of locally stored content in My Library.
