Re: [CURRENT ISSUE] Sims 4 Unable to Start, Already Running
After updating The Sims 4 and pre-ordering the upcoming expansion, the game will not launch and displays the error “Unable to start: The Sims 4 is already running” with error code [ed35e0ea:29f00e76:00000000:18a1dd51].
- I have restarted my computer multiple times
- Repaired the game
- Cleared the EA App cache
- Ended all Sims and EA-related processes in Task Manager
- Restarted the EA Background Service
- Ran the EA App as Administrator
- Removed all Mods and CC
- Logged out and back into the EA App
- Fully uninstalled and reinstalled the EA App
The issue began on January 15, 2026, and continues to persist. Other EA titles launch normally, including The Sims Medieval, which runs without issue, indicating this problem is isolated to The Sims 4.
