EA app installation error INST-3-1310 when launching FIFA 26 on Steam

Hello,

I'm getting error INST-3-1310 ("Unexpected error") when trying to launch FIFA 26 on Steam. The EA app fails to install (both automatically from Steam and manually).

What I've already tried (nothing worked):

1. Deleted all EA / EA Desktop / Electronic Arts folders from %ProgramData%, %LocalAppData%, %AppData%
2. Removed EA app leftovers from Registry
3. Restarted PC after each step
4. Disabled antivirus and Windows Defender (real-time protection)
5. Manually downloaded EA app installer from official site:
   • Ran as administrator
   • Installed to C:\EA Games (not Program Files)
6. Tried installing in Windows Safe Mode — same error
7. Ran sfc /scannow — no system errors found
8. Created a new Windows user with admin rights — error persists

System info:

• Game: FIFA 26 on Steam
• OS: Windows 10

Please help me resolve this. I can provide logs if needed.
