UI, options and all interactions inaccessible once leaving build/buy mode

Hello, unfortunately I tried this approach and no error at first but as soon as I put my saves back, the same issue happened.🥲 Just to add on, I even have the last exception it generated and I had Claude look over the last exception, I have played the sims for years and this is my first time consulting with anyone about an issue since I usually can solve them myself, however this issue is beyond me.  This what Claude summarized after reading this exception. 

Same error, no mods this time — Modded: False

That's the big one. The previous log had Modded: True, so we could blame a mod. This one is completely vanilla. This means the CareerPanelButton null reference during loading is actually a base game bug, not a mod issue. The UI is trying to read career data before it's ready, and EA hasn't fixed it.

It's also worse — more errors and a new one

Beyond the CareerPanelButton errors (which behave identically to before), this log adds a new error type: ClubPanelButton/HandleActiveSimGatheringUpdated() — so now the Clubs panel button is also hitting a null reference during the same loading window. This suggests the broader SimInfoTray is just not properly null-checking its data before the UI initializes.

There's also a deeper error trace in this one showing the full chain all the way back to NeighborhoodMap/OnLotLoadComplete() → OnAllLotClipsLoaded() — meaning the crash cascade starts from the neighborhood/world map finishing its load, which then prematurely fires off UI messages before Sim data is ready.
