Ashiefzt A dxdiag would be great; I'm sure that anyone from EA looking into the crashing would appreciate having one already provided.
Please also describe the context of the crashes, for example do they happen when you first load the game, or when you do something specific?
Edit: After further information was provided via private message, this user appears to have the formerly common issue with save data not populating.
This issue should be resolved now. For anyone still who is missing any neighborhood data (sims, lots, whatever), or whose game is crashing after the initial video but before loading into a household, you can try reseting your user data. If you're not attached to your save, please go here:
C:\Users\your username\Saved Games\Electronic Arts
and remove or rename the "The Sims 25" folder. This will reset all your in-game progress, and the files and subfolders should populate as normal now.
If you still see missing neighborhood data after a reset of the Sims 25 folder, please post in the thread linked below stating what is missing and what platform (EA App, Steam, Epic) you're using.
