Error Msg: 'walkstyle' (value: V) UnavailablePackSafeResourceError)

Have you confirmed that it's mod-related? See vanilla testing

This is the LE report that I got after I moved away my mods folder. This is another story now. 

Does this error occur only when you remove all mods?  If so, please attach the actual LE file that you get. 

Well, I followed the instruction from Gemini AI on the vanilla test result to validate/ repair the game in Steam Platform and I tested without mods again, there were no more error message regardless which household I played. 

The problems occurred after I moved the mods folder back to The Sims folder again. the following is the LE report. I think V pack refers to Vampire pack, but I owned that pack and I operate Vampire pack during my gameplay.  This happens every time I play the game after the recent game update.
