Help Needed: Sims 3 2025 Update Error When Loading Worlds

Ever since the Sims 3 2025 update, I’ve been encountering a persistent issue. Every time I try to access any world in the game, I receive the following error message:
“A serious error has occurred while loading [world name]. It is strongly recommended that you restart the application.”

I’ve attempted several basic troubleshooting steps—restarting the game, rebooting my computer, and checking for any obvious file issues—but nothing has resolved the problem. If anyone has experienced this error and found a reliable fix, your insights would be greatly appreciated.
